Anyone else ever notice?

when i check my tiller in paint using ellipses/circles drawn to match the limbs, by they almost invariably intersect right around the position of the arrow shelf.  Significant or coincidence?  Thinking if this is the case, i should use that process to place my arrow rest, rather than just deciding on a specific measurement above center.

I think that happens because you are very good
I try to line up ellipse/circle on my ELBs along the arrow line, this shows up any assymetry... It would be a bit odd if they lined up somewhere else. Maybe the pressure point of the grip? but I recon the pressure point is generally pretty close to the arrow pass.

lol right Del!

yeah that was what i initially expected when i started doing these (that it would line up at the pressure point), but it tends to be just above.  I think on my next i'll intentionally place the arrow pass at the intersection and see if it makes any difference.  I expect it won't make a whole lotta dif except maybe reducing handshock, a touch easier to tune, less likely to get out of tiller when shooting in, etc.  All those likely by small degrees.
