First of all, I understand that this topic is not specific to Hand2Note. However I do think that this topic is very much in the interest of Hand2Notes client base and the poker community in general.
I also felt that airing this on a forum such as 2+2 would attract too much attention to the PokerMaster app for obvious reasons.
I believe at least in my own games and clubs there is significant collusion occuring in some fashion for the following reasons:
a) Many of the 30/20 and 35/20 type regulars have played almost 15000 hands over the past 30 days. This equates to approximately 8 hours a day (!!!)
b) Many of these regulars who sit at the same table have played a very similar number of games in the past 30 days.
c) The 30/20 type stats make some sense for a potential colluder; having knowledge that the CO/BTN/HJ will fold incentivises an EP/MP player to open very wide, or knowing 3 other players hole cards clearly create very profitable 3betting situations.
I have always accepted that with this app there will always be some sort of collusion due to its nature; with that being said I think the magnitude of the collusion is so bad that some of the games are now completely unbeatable even at the 5/10 - 20/40 level.
I encourage anyone to share their thoughts here or to PM me. I personally do not know many people who play PM so would be interested to hear your own thoughts if you play the games regularly yourself.
