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!
