Sample size requirement to estimate sustainable BB/100 & 80k hand stat

[Duo]

Hello fellow 2+2ers,

I was wondering how large of a hand sample size will I need to accurately estimate my BB/100 in the long run? Is 200-300k sufficient? or 400k +?

How much BB/100 can a top tier player achieve in the long run in the 3/6 limits? Is 1 bb/100 achievable over a large sample size(ie. 400k+)?

Here are my stats so far for 3/6 and 2/4.





I am aware that I am too tight in the BB and I have been working on that the past month and defending more.

Please feel free to evaluate my stats and any comments will be much appreciated. Thanks in advance.
