Thinking about it more calling wider means we can plays more games/hour. so we can call even wider than that. A good range to still average the same win rate as playing someone we have over 60% equity against would would be 44+, A2s+ A4o+, QJo+, QTo, K8o+, JTs+, Q9s+ K6s+. We can call about 2-% of hands so on average matches should take 8 hands. We can probably do that in about a minute, not the 5 minutes I estimated earlier. Lets compare with a villian we have 60% equity against and matches take 15 mins. We already worked out $/h = 0.624. so (15*276E-(15*150))/25 = 0.624. E now would equal 0.547 so we only need 54.7% equity against any two cards meaning we can widen our range even further than previously stated.
Conlucsion, against somebody who shoves 100% of hands we can just call with only a 0.5% edge over break even and we'll still average the same $/h as playing a better opponenet who takes 15 mins to beat yet we win 60% of the time. I'm going to bed now but I mgiht try and work out optimal E that would give us greater $/h.
Sorry about the long posts with maths in them, just got me thinking and wrote down what wa sin my mind.
