I didn't have mine Crackerized, I had it MacRotechized.But the thing I find a little wrong with long distance tuning of a bow, it's set up for him.(I've watchedLen tune I don't know how many bows and do nothing but tear bulletholes and split X's. When the real owner puts his hands on the bow to shoot it that's a whole different thing. Different release, hand pressure, torgue... everything. Len has them shoot, points out form flaws and they become amazed at what a little hand adjustment does to their shooting.The final fine tuning has to be done with the owner. Yes he can get it to a starting point and make sure everything is plum, level, in tune if you will. The final tweeking still has to be done with the bow in my hand.
