My understanding of this is a little different, Pat. Not saying you're wrong, because I’m no expert in this. My understanding is that when the arrow begins to go through paradox, it first presses against the strike plate and then recoils away. The amount of recoil is one of the factors that determine POI on the target. I have used different types of strike plate material to change the POI. For a RH shooter, using a softer material, such as Velcro or rug rest will move the POI to the right, while using harder material, such as thin leather, will move the POI to the left. Using a thicker piece of hard leather moves the POI even further to the left, because the initial recoil and the physical movement outward of the centershot of the bow are additive. The hardest material of all would be the bare wood of the bow.
Aside from that, unless this is an old bow where appearance doesn't matter, either the strike plate or the side of the bow is going to pick up some wear over time. Strike plates are easy to replace, bows have to be refinished.
