i have been dealing with some high elbow issues in my form scince going up in bow weight, and also wondering why my nock point needs to be 9/16 up or a touch higher for good flight and bare shaft planing. first i shoot ad trads, which at the point end is a fairly large shaft, i also shoot 2364 ash shafts, a bit larger still. ive been thinking that a high elbow creates more pressure on the lowest finger, i shoot split, which in turn flexes the lower limb a hair more and raises the nock point, but on release that lower limb has more stroke in the same time as the upper and this acualy yanks the arow and nock point down a bit at the point of the arrow leaving the string.
i have done a few things like making my hook a bit deeper and just getting stronger, my elbow is usualy down where it should be and arrows fly wonderfull, but when i get tired i see some nock flight issues and start thinking about keeping the elbow down and equal pressure on the string and it all fixes itself, but my nock still needs to be a good bit higher than i am used to.
any one else see these things?
