Large databases and high winrates!

I read that 7ptBB/100 is supposed to be an 'average' winrate for a good player and 10ptBB/100 is a 'good' winrate! Yet I have never seen a large database for 100NL and above displaying these winrates. I suspect that 5ptBB/100 is a good winrate and anything above 10ptBB/100 is very rare long term.

So could any of you big winners please prove me wrong and post a 50k+(preferably 100k+) database showing numbers above 10ptBB/100. Also please include the number of tables you play.
