adjustments for 3/6 and 5/10

[PoorLawyer]

I have been playing 2/4 with a .25 ante and $1 BI for a while now and me do good. I jumped up and have been playing a lot of 3/6 with .5 ante and 1 BI, and 5/10 with .5 ante and 2 BI.

For some reason I seem to do a lot better at the 5/10 than the 3/6. Is this just the way I am running right now or is there some adjustment that I need to be making for the different structures?
