Are we not talking about what HM2 offers with "vs Hero" stats? Maybe I'm misunderstanding the request, but it seems the same?
I think not. But I don't have HM2, I have PT4 and this is the PT thread.
For simplicity, lets use HU (or ISO) situations; between us and any particular villain who also tracks, we should have identical stats for all the hands that went to showdown. Right? Well, sort of. For those hands that do go to showdown, the stats should be the same, but all those that never get to showdown still produce stats, and they may (or may not) be very different from our POV vs his POV.
The stats we currently get are our own lifetime, or perhaps session stats, but they may be polluted in the sense that they include all stats against all players, and all we want to deal with is our stats against that particular player. But what we really want is to see what that player is seeing in their stat windows as he plays against us. It doesn't seem like it would be all that difficult to calculate and display an alternate HUD as if we were the villain looking at us.
So it is sort of like Villain vs Hero, but we get to see what Villain sees in his HUD. Stuff like, How often do I fold to his 3bet on the turn?
It would probably be good to separate this discussion out of this thread where it could be parsed to death until we had a good description of what it is we been talking about and desiring.
