re: Poker & HUD, Is it believable on tournament?
If the HUD could split the information depending on which phase of the tourney u're playing (like, early stages, mid stages, bubble, itm and FT) it would be a lot more reliable imo, since ppl change the styles during the tourney (is there some tracker that do that?)
I like using it to concentrate where to look. Like, if u see someone with 60% VPIP, let's see some of the showdown cards of this guy, the range he is playing must be huge.
Then I usually do notes on the player. It really helps me to focus on where to look.
And for the number of hands to be reliable, i would say that with 50+ hands u're starting to have a solid stat representation.
