Should have checked back in sooner.
Consolidating the previous math:
E-factor/AV = 48 * 2.5^[3.322(log(mm RHA) - 1.4049)]
3.322 ~= 1/log(2)
1.4049 ~= log(25.4)
Checking , the formula returns slightly different values thanks to rounding:
300mm = 1255
90mm = 255
113mm = 345
180mm = 639
sub 1% differences are OK, I think.

Has anyone converted this formula to an Excel formula yet?
