Let's assume we have a bow with a nice linear Force draw curve that gains 2# an inch except it stacks so the last 5 inches of draw go up to 3# per inch. Will this bow shoot just like one that doesn't stack? That is one where the FD is a straight line gaining 2# per inch right up to full draw. Put another way does the "stack weight" do anything except make it harder to pull?

if both bows pulled the same weight, the stacky one would have less speed. Less area under the force-draw curve. less overall work done by the arm.
stacky bows also will do worse when underdrawn a bit compared to a non-stacking bow short drawn.

Not sure I'd call a bow with a linear force-draw curve 'nice', but I suppose it could be worse.

3# per inch for a 50# bow is really not bad, 4# you would start calling it stacking, 5# is starting to seriously stack. Usually a bad string angle or a bow that has taken a lot of set and has low early draw are the ones that might stack like that.
