I suggested a base of 2100 Kcal on non-training days, and 2700 on lifting days, and then after two weeks adding 400 Kcal on lifting days and 200 on off days. This fits the way a high level coach would have him progress out of the diet and allow him to make adjustments based on feedback, something he seems quite well at doing. I am pretty sure he can use this construct effectively.
As for your guarantee, it isn't worth shit, I have seen people his size and slightly bigger gain on that much and I do this for a living seeing 20-40 clients every two weeks, a good fraction of which are in the same boat.
@DG831: as MAF14 suggests, check out Shelby's article:
and this one too:
They fit your situation (you said you want to limit fat gain) and leave room for future tweaking allowing you to make feedback based decisions which you seem to have demonstrated the ability to do.
As for my recommendation for a possible step after the 4 week progression I recommend, 25g per other meals and possibly upping fat a bit are your next options. If you choose to do this feel free to PM me at that time if you want to briefly discus your next move.
