The grip area of the bow at that point is a 4" flat area.
I shoot a high straight wrist grip so it's very close for me.
For someone who shoots a low heeling grip, I'll let the pull rope drift about 3/16th to the bottom limb, left limb in video.
Whichever side the pull rope drifts to is the stiffer limb.
Then the guy will shoot it and if need be we can adjust the tiller a tad but normally nothing needs done.
Kenny, ya ask the guy how he shoots and or watch him shoot.
And every factory bow a guy buys has to be tuned by adjusting the nocking point up or down.
And by adjusting the nocking point up and down you are pulling the string in a different place to "balance the limbs" to get the arrows to fly good.
I see many folks pulling the bow dead center on the tree and removing material to get the bow to a positive tiller 1/4", which seems to be the standard tiller for years. It doesn't make sense to me to tiller a bow by pulling it dead center then when they shoot it they are pulling the bow 1 or 2 inches above the point they tillered it at, especially for split finger shooters. The limbs can't be bending the same pulling it dead center then pulling it 1 or 2 inches higher!
But everyone has their own method and if it works and they are happy then so be it:)
