Drift Science and Compatibility

In (somewhat belated) honor of K-Day, I submit unto the fandom a canon-supported theory of drift compatibility and testing, based on PPDC officer UIDs.

ex. 1 (graphic)

ex. 2 (additional canon examples)

Raleigh Becket   R-RBEC_122.21-B
Mako Mori   R-MMAK_204.19-V

Stacker Pentecost   M-SPEN_970.89-Q
Hercules Hansen   R-HHAN_832.84-G
Chuck Hansen   R-CHAN_512.66-D

Newton Geiszler   S-NGEI_100.11-Y
Hermann Gottlieb   S-HGOT_471.120-V


Harlowe-Sheehan-Parker Compatibility Index: Ranging from 100 to 999, the HSP index indicates range of compatibility with other drift-capable individuals. The lower the number, the smaller the range of potential drift partners for the individual in question. A person with a lower HSP score is less flexible in dealing with dramatically different brainstyles, and requires a drift partner with either significant shared life experience, a high mutual degree of trust, or a close CORO pattern. Someone with a higher HSP score is significantly more adaptable to drift partners of disparate backgrounds, experience, and CORO profiles. Observe above how Stacker Pentecost and Herc Hansen have extraordinarily broad indices and thus may drift with nearly anyone.

CORO pattern: CORO patterns are shorthand for cognitive architecture, how a person thinks, processes input, makes decisions, etc. The range for CORO patterns is 1 to 99. If two people have the same CORO, they can establish a stable drift connection. Whether or not they can sustain a drift is a different matter, but generally being within twenty points of each other is enough to have a solid drift whether they get along or not. Mako and Raleigh are two points apart: they are Jaeger soulmates. Note that Stacker and Herc are five points apart: they are also Jaeger soulmates. Observe that Hermann’s CORO number is 120. The zero stands for a medical exemption, recommending against drifting due to his illness. Otherwise, he and Newt are a point apart.

Juno Keeler Trauma and Stress Tolerance Rating: Ranging from A to Z, from most stable to most easily destabilized, the Keeler rating (also abbreviated KTSTR, pronounced ‘kitster’) measures emotional volatility and resilience, and is also used as a general indicator for how likely someone will go to pieces inside the drift. Less precise than the HSP index and CORO pattern, the Keeler rating is based on in-person psychological evaluation and consideration of any previously lived trauma and/or extant mental illness. Note that a high Keeler rating does not contraindicate drifting, merely offers a warning for potential difficulties. Newt’s high rating is likely due to a mood disorder; Mako’s may be attributed to Tokyo. Observe also how close Raleigh and Chuck are to the beginning of the alphabet. Raleigh arguably had a fairly stable upbringing and, especially given his rating was handed out pre-Knifehead, a mature and level emotional response. Chuck might also have had a stable childhood before Scissure, and his low Keeler rating indicates he is not overly damaged by the experience, he isn’t emotionally-compromised, he’s just an ass.

IF YOU FEEL INCLINED TO USE THIS IN WORKS OF FICTION: I offer this drift science to the fandom for free, no catch, under a creative commons license. Adapt as your fanfictional needs require so long as no profit is involved. I thought the idea was too good not to share. If you do use it, please credit and/or link back to me, and feel free to message me also because I want to see what you do with it.

This is canon-compliant until canon proves otherwise. Go forth, beloveds, AND CREATE!

When Marie Tharp suggested the idea of a rift valley deep in the Atlantic Ocean, which supported the then-controversial theory of continental drift, her hypothesis was dismissed as “girl talk.”

Now she’s credited with creating one of the first comprehensive maps of the ocean floor, though it took 20 years after her its publication for Tharp to be properly acknowledged. 

— Meet the woman who defied convention and male doubts to map the ocean floor


I use to think about this scene a lot. Specially about Hermann’s face here. 

I believe Hermann didn’t want him to speak not because he thought Newton’s idea was stupid and illogical. No, I think Hermann believed in the bottom of his heart that Newt was right, that sharing a neural handshake with the kaiju would give them some answers, but it would probably kill Newton.

So how is he going to stop Newton from doing this? He tried to knock to his ego (“Don't embarrass yourself”) because offend him might be a better way to stop him than saying “Please Newton I worry about you don’t do the thing”. But they’re not like this.

Whatever, saying that didn’t stop Newton. He is mad and he even turns off the computer in a very angrily way “Seriously Newton, you are going to risk your life like this?”

And what can I see on Hermann’s face? Well I see fear. And a little bit of angriness. I mean, if you focus on him, he looks anxious. He is shifting and muttering “No” and shaking his head a little. 

Because If the Marshall and Herc do believe Newton and they give him the green light, it’s all over. Newton will be dead and he won’t deal with that.

And when Pentecost says he wants Hermann’s information, he could not be more relieved. When he salutes the Marshall and says “Sir” I feel it’s his way for saying “Thank god”.

And then he smiles. No like, he is literally smiling AND looking at Newton, and things are normal again. He starts mocking Newton and Newton is pissed off but let’s remember Hermann’s last words:

“You’d kill yourself”

Hermann cares. He always cared.

(Sorry if my english sucks but I really had to write that down bc I have a lot of feels about these fucking assholes)

Important Science News: Pacific Rim-Style Drifting Between Two People Is Totally Real

If you’ve always wanted to pilot your own Jaeger (and let’s face it, who hasn’t), have hope; for the first time ever, a study has proven that two people can transfer thoughts between their brains without the help of talking, writing, or any sort of invasive technology. I think I would like to name my Jaeger “Feminist Killjoy.”

Scientists from Duke University published a study called “Conscious Brain-to-Brain Communication in Humans Using Non-Invasive Technologies” this summer, in which they establish for the first time ever that “mind-to-mind” communication between “conscious activity” of two people is entirely possible. 

DRIFT SCIENCE APPENDIX A: PPDC Officers and UIDs, 2016-2020

The people have spoken! Everyone who liked and reblogged my post about drift science, THANK YOU, I am so flattered! I do read every single comment and a large number of the tags and I couldn’t help but notice a trend: y'all want to know UID numbers for canon characters that didn’t have one published.

Okay! I wrote up more than a few for my own works-in-progress, and I see no reason not to share. Organized by guesstimated start of service/Academy year, then by surname, I present the complete list of canon PPDC officers thus far, including canon UIDs for any and all inclined parties. Enjoy!

*Speculative guess, non-canon
**Sasha’s canon UID is SKAL. This could be a typo, but I have interpreted that she entered the PPDC before she and Aleksis married
***Canon assigned one number to the triplets; I gave this number to Cheung and extrapolated for Hu and Jin’s UIDs.
****Mako’s canon age is inconsistent across different media; I have chosen the April ‘03 date of birth and the same Academy class as Chuck.
*****Mako’s canon UID seems to follow 'surname’s first letter, given name’s first three letters’ format. This seems likely to be a typo, based on observation of the original UID assigned to the Wei brothers, but arguably could be intentional, in respect of her being a woman of East Asian descent, belonging to a culture wherein surname is stated first. I have chosen to realign Mako’s Ranger ID to match the format of other PPDC officers’, and written original IDs for the other East Asian rangers in the same style. That being said, I am not Asian, and if told this course of action is inappropriate I will immediately revise the post to better align aforementioned UIDs with Eastern naming conventions.

As with the drift science, this reference is free for fandom use according to Creative Commons Usage. If you want to use it, please tell me, I like seeing how my ideas travel!

About those Drift Science posts circulating...

I would just like to point out that ONLY the PPDC officer IDs are canon.

Everything else is 100% fanmade.

There is no such thing as:
Harlowe-Sheehan-Parker Compatibility Index
CORO pattern
Juno Keeler Trauma and Stress Tolerance Rating
in canon for Pacific Rim and Drift Science.

Google it, and the only reference you will find are those two posts.

While this is very creative meta, and everyone is free to adopt that classification system if they so wish in their own writing; I believe it is important to point out that the only canon-compliant information is the number of the PPDC employees identifications.

Those serial numbers could mean anything.

Like I said, I do not mind people coming up with their own classification systems and theories.

But adding terms such as: “canon-compliant”, or “canon-supported theory of drift compatibility and testing” is misleading.  It suggests that the ID numbers are related to drift compatibility and testing results in canon, which is not the case.

It also suggests that Harlowe-Sheehan-Parker Compatibility Index, CORO pattern, and Juno Keeler Trauma and Stress Tolerance Rating are part of canon Drift Science material, which is not the case either.

Here are the two posts I am referring to:


Fanmade official looking graph based on original

Once again, great theory, and obviously a lot of work and thought went into those, especially the graphs giving them an official PPDC look.  Please feel free to use and enjoy them as much as you want to.

But hopefully, people that do not wish to adopt that classification system, and prefer to give their own interpretation to the ID numbers, won’t start getting stuck in arguments that they are refusing to respect the canon classification involving the CORO patterns etc.  They simply do not exist in canon.

Thank you for treating everyone’s own creativity equally and respectfully.

Catch you all in the Drift!
