Kip: I always hesitate to give advice, but since you asked...here's my humble $0.02.
I would anticipate that those weaker tips will only continue to worsen. As you approach that 90 degree angle between the tips and string, you're changing the mechanics of how they're bent (which is why you get stacking). As they weaken, they'll continue to take on more of the work. As it stands, it looks like the inner third of each limb is not quite bending it's fair share, even with the reflex that's built in there. Get that area bending a touch more, work out that soft spot on the left limb, and then see where you're at after 70 more shots. If you come in low on poundage, consider tempering the belly or just leave it be!
Alternatively, you could add a belly lamination under those tips to keep them stiff. You could make them as long as 10-12" or at least just past the weak area. It won't take much wood at all to stiffen them up. This will transfer some of the load to the inner third of the limbs. Combine that with some wood removal the first 8-10" out of the fades and you may find you come in right back on target.
At the end of the day, I'd say send a well-tillered bow that's a few pounds too light than one you're not satisfied with that came in right on the buzzer for weight.
