Wow man... that's quite the quick build and quicker drop. I strongly suggest more buy-ins available within your bankroll, especially for 6-max. You must have dicipline to move down when you are dropping below your prescribed level. Jesus Ferguson dropped two levels I believe during his first $20,000 quest online.

On a personal note: I finally made it to the 2.5K mark on 25NL (took about 2 months). I lost 5 buy-ins on 50NL in a few hours and now I'm back at the 'ol fishing pond (well, not that old). I played way out of my style ie. calling with middle pair OOP with tons of players, paying off draws big that hit, loosing to sets with TPTK, loosing to JQ with A7 on a 689T board... I blame half on variance, half on fishy play on my behalf. It was weird.. the first big hand I was involved in was 5 minutes in (the last straight hand I mentioned). I was called a fish, for the first time since I started playing online.

Give it a few days, and I'll be back for another interview for my promotion again.
