i have a parker extreme ultra lite 31, and last year i bought a whisker biscuit and had it put on. Question is, when i nock the arrow, the fletchins are about a half inch or less inside the biscuit. Is this something that i need to worry about? do i need to slide it forward a tad bit or is it fine the way it is. I had a archery shop installed it, but i havent been shooting very consistent and i am just narrowing it down to make sure it just isnt me
