I think the first big loss of moisture is the part not to force, I'd say a month give or take depending wood and environment. That's when a majority of the potential damage/ checking is done. Then get it near your final specs, back it, and clamp it in the caul and watch the "paint" dry. With the time line we have you shouldn't need to force it that seriously. I'd work on a plan B bow along side of that build so you don't get impatient during those times when the waiting matters.
