I guess if everyone is in push fold mode you could assign shove ranges to them all and then calc the chance they will pick up those hands and the chance you'll get a hand you can shove with?

Then you'd compare the EV*(chance we get to shove)*(amount of chances) of that shove to the EV of this one. Seems hard because people's ranges will change as they get shorter/bigger stacked. Maybe do it for one orbit or something?
