I think he "lost" it after Diamonds & Pearls...The thing is, as wack as say "Jughead" or Tony M was, P still had the "goods" as evident by "Money Don't Matter" and the like...

After that it was hit or miss for P...Sometimes he knocked it out the park (The Truth, Emancipation) and other times he struck out epically (Chaos & Disorder, Rave Un2 The Joy Fantastic)...
