I think good dynamic balance creates an inherently tuned bow, better arrow flight, less hand shock, more efficiency, predictability, stability, tiller less likely to shift, and more. I don't understand why folks work on their bows with disregard to it... like they don't even want to know. Ignorance is bliss I guess
And I don't understand why folks assess and adjust the relative limb strength of their bows while pulling the string from the middle of the handle when it's impossible to shoot it that way. Think it's easier? It's not. Not with all considered.
Neither do I understand why others would adjust limb strength to achieve a predetermined measurement at brace and assume it will act a certain way. These are wooden bows with inherent irregularities, some of which are visible and some are not. We should adjust them according to how they act as they're drawn relative to our personal fulcrums, not according to how they look laying braced on the bench.
I don't wait until the last few inches to adjust dynamic balance. I begin watching it from the first light tugs of the string while on the tree. The sooner the limbs are balanced in regards to the shooter's fulcrums the better in my opinion. I don't wait until later in the tillering so I can try to feel it, or take pictures to study, or stand in front of a mirror to inspect it. The first time I draw a bow by hand I fully expect it to be 100% balanced. I know it will be because I made it that way from the beginning. I also know right where the arrow needs to be placed on the string from the first shot.... because I made it that way. That determination was made before the string was tugged on for the first time. That arrow position determined where the nock point goes, where the string hand goes, and where the hook goes to pull it on the tree. Creating optimal limb harmony relative to our fulcrums assures good arrow flight from them as a matter of consequence... among other good things.
