trends at party poker

Most players in the know have figured out that Party is not dealing random cards.I have a friend who says he has noticed another trend.After getting ahead $20 or so in low limit he hits a wall.From that point on he feels he is a cinch loser.BUT.........if he leaves the game,logs off of Party,logs on again and plays,everything is back to normal.Or at least as normal asit gets at Party.Anybody else notice this??????? Don't even bother leaving a message that Party is squeaky clean.BS.
