bugr

I’ve invented a new math formula

[s*(ry)^x]

s = size of a bug
r = movement rate
y = fear/hatred of humans on a scale of 1 to 10
x = -1 for fear, 1 for hatred

using this formula you can calculate precisely how scary a bug is relative to another bug 

fly: [1.2mm*(5mph*5)^-1] = 0.048 

moth: [13mm*(8mph*2)^-1] = 0.813

cockroach [40mm*(2mph*4)^-1] = 5.000

wasp [13mm*(5.6mph*8)^1] = 582.4
