Brent,
I'm not a "walker", but based on the number of folks who use this method, I would say the answer must be 'no". And not to drag this post "off in the bushes", but I have a related question. How does it not add noise and vibration? It essentially appears to be purposely taking the limbs out of sychronization and progressively putting more load on the lower. Given that the nock point is fixed and you are moving a 3-under tabbed release further down the string to equate cast with distance and not changing anchor, how does it accomplish this? It looks to me like the limbs not returning to brace height simultaneously would slam the nock end of the arrow off the shelf every time. Hopefully someone will enlighten us both.
