Pokerdb and the IRS

I'm in no way a tax expert, but the little bit that I've read suggests you need to report your winnings per session, and that one day is a reasonable length for a 'session'. So while you aren't allowed to report only your net profit unless you file as a pro, you don't have to report every single tournament win, just the amount you win or lose in a given 'session' (day). Pokerdb, then, won't necessarily show even the minimum amoung that one ought to be reporting.

Once again, that's only my amateurish understanding, and I'm in no way confident this is correct.
