Was the creator a FL specialist then ?

Just finished my first cash session using PT. I played 104 hands of $2NL and won $1.28. A quick calculation gives me a win rate of approximately 60BB/100H (it's actually 61.54) but it's being reported as 30.77, exactly half the true rate ???

I'm currently playing DON'S on this site. On checking the tournament stats on completion of the game I'm finding a rebuy keeps being added, effectively doubling the buy in. Is this a known problem ?
