I don't think what you understand is that it could be a problem with other parts of the bow that are causing the limbs to break, when a limb cracks it definitely doesn't mean that it was just a problem with the limb. If your bow has a slightly bent riser that causes the limbs to break and BowTech replaces limb sets after limb sets, they are out of the money that it took to make those limbs, and for what? The would then be fixing a part that they warranted that isn't actually at fault.
