what do you think about OP's 40% VPIP? It seems to me that in low-stakes online play you'd want to play tighter than that, but I know very little about poker strategy beyond what I've absorbed from seeing people talk about it.
It's a fairly meaningless stat without knowing the number of the players at the table. At a quick glance he seems to be playing 6-max, but sometimes 3-handed. In any case 40% is within the reasonable range for 6-max.
Assuming they are playing 6 max with full tables 40% vpip is egregious and I do not see how they could have a winning strategy playing like that. (Looking at their results they are not winning).
To be fair, 1k hands is a pretty meaningless sample - I think most pros would say you need at least 50k if not 100k hands for the results to be any reliable signal as to whether or not a player is actually winning or losing in the long run.
