C*(1-A)=A

C*1-C*A=A

C=A+C*A

C=A*(1+C)

C/(1+C)=A

At C = .4 (Max rank) we get:

.4/1.4 = A or A = .2857

All your guess and check got you really close.

Rank 1 (28.6%) = 22.24%

Rank 2 (33.3%) = 24.98%

Rank 3 (40.0%) = 28.57%

Not a big rise in % health kill zone, but for fighting health tanks it probably matters.
