I can site several real world examples the physics makes sense in my mind but, I am not sure I possess the technical language to explain it but, I'll try.
First real world example- Easton's tuning guide. If you look in the arrow charts they provide they have one for compounds with a release. They make a note for finger shooters that you need to move up to the next bracket in arrow stiffness because of the increase paradox fingers introduces
Real world 2- The renowned archer Joel turner use a thumb release which he describes a inducing very little paradox. He notes that he had to drop a substantial amount of spine in order to get his arrows to fly correctly because of it.
My lame attempt at explaining why this is so-
when the bow string leaves you fingers it forces the string away from your bow and the arrow INTO the bow. The arrow then springs back again (and again and again several times to a lesser degree) around the riser. The harsher the release, the more violent the initial bend and following level of flexing, the stiffer the arrow needs to be to compensate. With a clean release the initial bend is much less making a heavily spined arrow show stiff as it had less lateral force exerted against it. And the recovery bounces it left(r handed shooter).
