Firstly, I think the number of stats is a big improvement in HM2. But I find it ather strange that you already sell a product without stat definitions available... I've read that those are coming (way too late imo).
There are numerous positional stats, eg call open btn vs EP raise and SB 3b vs MP. Very interesting, but how does that work out in 6 max vs 10 max?
In HM1 there are numerous topics about FR vs 6max stats (eg http://forums.holdemmanager.com/hold...-better-2.html). Therefore it is highly important to know what positions definitions are used in HM2.
I think that many players would prefer to see positional stats that are not overlapping (EP in 6max is MP in full ring). Especially when you are at an 8 max table with 2 people sitting out.
