My mistake, gaw stopped their mining idd. My numbers are from the last payout I received. You can even see people receiving payouts from them mid Jan: https://bitcointalk.org/index.php?topic=768931.msg10203950#msg10203950

If something pays you 100% accotding to a calc, there's your reason to become worried.

AFAIK and as far as I understand: mining calcs are built as tools to PROJECT mined amounts within a certain period of time in perfect conditions like all shares are accepted, equipment is always @ 100% hashrate and pool efficiency is max. Now tell me, where in the real world you have seen a perfect system?
