My roll is 800$ after being up $150 from cash games and $600 from tournament winnings. I am playing SSS. Why am I killing .10/.25 FR games but can't do the same at .25/.50? Considering my roll, where could I be playing?

Below are my graphs and stats for the two levels. I'd appreciate some comments.
