Can we trust our stats?

[Laetus]

A: How many hands do we need to get an aggression factor that we can "trust"?

B: How many hands do we need to get an VPI and PFR that we can "trust"?

I think 50 hands is enough for A, but I don't know how many hands we need for B.

Total Hands: an incredibly important number, this tells you how much trust you can put in all the other numbers in your HUD. At about 50, numbers like VPIP and PFR start to be meaningful. At about 10,000/VPIP you can start to rely on total aggression (e.g., 200 hands for a player with a VPIP of 50, but 500 hands for a player with a VPIP of 20). W$SD doesn't really lock up for several thousand hands, so treat it with a grain of salt, but WtSD becomes meaningful noticeably faster.

How many hands it takes to get a comfort level for VPIP and PFR is dependent on how high their VPIP and PFR are.

If someone has a VPIP of 75, you can see it with pretty good confidence after 20-30 hands. If they have a VPIP of 7 after 100 hands, they could easily be a VPIP of 15-20 on a dry streak.

Is there a thread or somewhere online that lists the statistical ranges for different types of players in different categories, and for the stats of more famous players or "stars"?

Does anyone ever "reset" their stats on purpose? If we have say 20K hands on a player and they significantly change something about their game it's going to be a long time before we notice based on stats alone.
