Tuned arrows- you bet! That's why the HS can be so valuable just FOR the reason that it CAN shoot an arrow in the same hole over and over. You then have a baseline for consistency across a group of arrows.

The individual archer has many variables when switching from one bow to another. Using the same arrows? Is the new bow faster, more power? Is that potentially different power equating well to the spine of the arrow? Same arrow rest? Ok, so lets say the archer likes some new cam for HIS shooting style.

What about another archer that has tried many cam configurations and thinks a different cam style works best for THEIR shooting style? Both will claim that their perfromance improved when switching to their respective new cam styles. Who is right? Potentially both are. They may both be right for their individual styles.

An average bowhunter that has used the same bow for the last 10 years and finally decides to buy ANY new bow on the market will most likely be much happier with the new bow vs. what he had. The average archer doesn't get to try enough different cam styles side by side to deteremine what ultimately works best. And even if they do, it is only what works best for their personal style. They may get to try a few shots of different cams in the store- but no real in-depth tuning to the "nth" degree to eek out every last potential point.

What I like may not be what you like.[&:] That's why manufactures offer 31" bows up to 45" bows. Rather harsh draw cycles for ultimate speed, or round wheels for smooth target shooting. Heavy, light, and everything in between.
