So, if I understand this correctly, the objective is to NOT have the top and bottom limb bolts equally screwed in(for lack of a better description). Say a bottomed out bow has a 70lb pull weight, then to adjust tiller you would back off the top bolt until correct. Once correct, in theory, you would not be shooting at 70lbs anymore. Am I right? The supposed increase in arrow speed would be from the bow working more efficient?
