no because the point is if you have anything less then 500 hands on a player hud isn't that useful since none of the data can be statistically significant there is 1326 pre flop hands in poker hence really you need at least 10s of thousands of hands before it can be statistically significant although you can more less get a general idea with statistics from several hundred. anything less and there is such a scope for variance that the statistics don't mean a great deal.
the more traffic there is the less likely you are to bump into the same players again and with a small sample of hands I wouldn't rely on hud statistics at all I can generally tell whos going to call of light and whos going to call of tight etc based on plays ive seen earlyier in the sit and go and similar things would probably apply to cash.
and hud doesn't really seem to give me that info until ive reached the point of several hundred hands at least.
hence your own reads before you have large data could be trusted more.
however once you have a very large volume of hands on an opponent you can be more statisticly accurate on whats going on with them with a hud then you can from your own reads.
I generally notice though that for me if I have a large sample of hands on a player there a reg and therefore they pretty much know more or less what they are doing and thus I can predict without a hud anyway, thus at the moment hud for me pretty much just tells
me who the regs are and I make notes if I see a regular do something odd.
however when i get to high stakes i am sure hud will have much more uses
