If you're doing SS maplefuturist, you should be definitely be eating more than 2600 calories. That's really nothing. Just browse the SS articles for 10 minutes and you'll see Rip berate people for eating that few calories. I've done it since late April and I went from ~180 to 210. Yeah, 2 months with a stall is really damn quick. As long as you started light enough and loaded at a reasonable pace, you should keep going for a while. Not sure how any of that has to do with SS since drop sets, super sets, and short breaks aren't part of it. Sadly, to most people it is a magic program because they've been doing useless shit for years. I'd rather have an overzealous SSer critique my SS form than a x-fitter try to preach to me about his program.
