Len,

I'm not really sure what a false tune is. Are you referring to a paper tune or to a type of group tuning? I tune my W.B. just like I tune every other rest I've ever had and it works great. I group tune at 20 and 40 yards. Then, I bareshaft tune to get my spine where I want it. It sometimes takes a little time to get horizontal and vertical arrow placement correct at each yardage, but in my opinion a bow is not tuned until it is group tuned.
