For what it's worth, I ran SS (wichita falls) at about 245 and the same bodyfat. I stayed the same weight, so I must have recomped quite a bit, though fat loss was not my goal. I did not do GOMAD, or even drink much milk: lots of meat, veggies, and fat. From what I understand, I may have hit the final stalls a bit early (maybe 10-20 lbs), but I'm also older than most of the folks that do the program, so I suspect that's just as likely the culprit.
I will say, however, that I enjoyed the program more when I split it up as:
A, rest,B, conditioning, rest
C, rest, A, conditioning, rest
B, rest, C, conditioning, rest...
I think it was the added rest and the quick progress in the conditioning. Conditioning normally involved some combination of a mile run, complexes, or hill sprints.
So, it can be done.
