4/5/6 betting continued

i realize that my assumptions may not be realistic. so, here are some charts that should give an idea for how the different inputs change the situation:

the top chart is the original scenario, the bottom uses a tighter opening range for co/btn:

you can see that the game-theoretical optimal strategy does not depend on co/btn opening range, while the performance of any strategy does.

if the bb has different 3b ranges (as klink pointed out, most probably will), the optimal strategy will change. here are some charts that show different ranges v. different co ranges:

i didn't take the time to find the optimal strategy for each, but you should be able to approximate from these.
