Thx, i get the calc; trouble is, MMM appears to be presenting it as a one-size-fits-all solution, whereas, it's only the scenario you use as ur example that holds true.
e.g. if he open-limps in from CO and i ISO to 5bb (my "standard"), then
EV = 0.57*2.5 - 0.43*5 = -0.725
I'd have to drop my ISO raise to 3.3bb in this spot to make it +EV in a vacuum; is this something i should be considering?
