basically if your in a 5-6 hour tourney late say 50 players left vpip you want above 20% at that time...... or that is what i shoot for 24% of hands as an average.... means i have voluntarily put in the pot 24% of hands..... if a lot lower means im struggling and a lot of times is ok to shove to add more chips if way above it means im hitting a ton of hands and to bully if possible
to see what others are doing vpip is important but you need a large amount of hands to be sure of the player type if is 100 hands and is high vpip villain could be very aggressive or could be very hot I dont like to use pt4 for under 1k hands live play i usually turn off pt4 honestly and only use to make sure im playing my hand history correctly not soo much on what some other villain is doing primarily cause i only play one table vs that villain at a time and i can read their history without a hud so im comfortable about my reads without stats on how they are playing vs me if we been on same table a bit....
in america is honestly less poker rooms so I feel can honestly know most opponents with /without notes from my history of over 15 years of online play
but if dont have history can see how they are playing pretty quickly and will act accordingly and color code them or note them
