typical gross wins for US Taxes

[Bubu]

I would like to get an idea of what typical gross wins are. I want to use this to figure out what tax liability to expect at the end of the year. Say, for example, your gross win is rate is 9bb/100h and the losses are 6bb/100h, so that the net is 3bb/100h. Could you please list your sample size and an idea of game limit.

Thanks !
