I have the qad ultra rest hdx installed on a hoyt element. Although the windage adjustments are self explanatory, I'm unsure of how high or low this rest is supposed to be? The rest does have the micro adjust marks.
If you have your knocking point set then just make sure your arrow is level and set the rest there. Make sure the forks are in the full upright/draw position when doing this.
With your launcher up, as the arrow sits accross the shelf it should be level with the berger button hole... I normally set the knock point on a drop away like your setup about half a bubble high. I use a string and arrow level but I'm guessing it's 1/16 to 1/8 high from the arrow being level.
