plane proficiency bonus:
exp = internal proficiency, 0 - 120 (?)
amount of exp probably correspond to displayed ranks:
0 <= exp < 10: no rank
10 <= exp < 25: |
25 <= exp < 40: ||
40 <= exp < 55: |||
55 <= exp < 70: /
70 <= exp < 80: //
80 <= exp < 100: ///
100 <= exp: >>

accuracy:
avgExp = average internal prof of all planes
baseBonus = sqrt(.1*avgExp)
additionalBonus:
avgExp = |:   0
avgExp = ||:  1
avgExp = |||: 2
avgExp = /:   3
avgExp = //:  4
avgExp = ///: 6
avgExp = >>:  9
if at least rank |, acc bonus = baseBonus + additionalBonus

crit:
assuming cht1 is crit rate bonus, cht2 is crit damage bonus (these are calculated but not used in Kai)

///: +5.6 to cht1, +(sqrt(exp)+5.6)/200 to cht2
>>: +8 to cht1, +(sqrt(exp)+8)/200 to cht2
bonus to cht2 doubled if plane in first slot
lower ranks give no bonus
