Looking for a little HELP...

I am looking for answers. Each time I try to move from $100 to $200 either 6 max or FR, I am getting destroyed. The thing is that I am killing $100 and lower.

6 max-------:100-------------- :200
Stats---------:19.3/13.1----- :18.3/11.3
BB/100-----:13.25------------: -5.5
FR------------:100------------: 200
Stats--------:17.3/7.5-----: 15.6/8.4
BB/100----:11.5------------: 1.46

These stats are over several thousand hands at each level. I move up and lose then I rebuild, then I take another shot. Is there something about $200 that I am not getting? I was beating the $200 at Party pretty good. I don't understand why I am having so much trouble. I don't think the level of play is that much different at 6 max. The $200 6 max game is the only one that I have ever been a losing player at.

200 is much more difficult than 100. That being said, full ring is so easy you should be beating it. 200 6 max however is actually a fairly tough game. You better take help of Calculator.
