Useful sample size?

[Orthoguy]

I purchased HoldemManager 2 days ago, and had the trial version for about a week before that. I've been looking at the reports available. I realize at this point the reports are probably useless due to the small sample size. At what number of hands do they start to become meaningful?

preflop youll be able to notice a really loose player or a really tight player after 100-200 hands but 500 hands might be a better sample to get a proper indication. Post flop it depends, things like cbets etc that happen alot might need 500-1k+ hands for a reasonable idea but things like raise flop or raise turn might need several thousand hands before it happens enough to make an accurate decision based on the stats
