SB, the WB rest is a very easy rest to tune. You can start off by the Mathews spec of 13/16" from the riser for your left to right, and I find that pert near level on the arrow gets you real close. I personally stand about 4 to 5 feet back, because at this distance an arrow cannot correct itself. A poorly tuned bow will give good results out past 10 feet because the fletchings have time to correct the arrow. If you want good Bhead flight, then tune close. Also, I strive for perfect tears. An arrow going slightly left, or right, or up and down thru a WB is losing energy. BTW, if you get a perfect tear, then on the next shot you don't, it is your form. When I tune, I mess with things until I get that perfect tear. After that, I set my sight, and forget it. Hope this helps.
