King of qualifiers

I am seriously considering changing my Poker nickname to QualKing or KingQual or something along those lines. Even Rooty jibes me about my qualifier take downs.
When I want/need to get into a big buy in tourney, I have no difficulties taking top spots in the numerous qualifiers. Either MT or SNG. Where everything falls apart is the actual tourney I parlay my way into.

Why is it I can do so well in these qualifiers?
What is missing in the big game?

I have had a great run this weekend of securing seat's into the PPM IV tournements.
Yesterday afternoons Semi Final, and last nights Super Satellite. Placing in neither.
And once again today, I take down a ST SNG Super Satellite Qualifier.
Tonight's PPM IV Super Satellite is my last shot at the boat, wish me luck...
