SS -
As I said, everything you're saying is true, but how much does it actually mean (score wise) to your average or even above average club shooter? Remember, the first 300 blue face was recorded in the late 1960's, (1968, IIRC) with a bow that would be considered obsolete by today's technology standards.
The top tier shooters today might be "better" than we were 50 years ago, but I'd be willing to bet the average club shooter then could easily out shoot the average guy today despite the "better" equipment.
The analogy I always use: high octane fuel is "better" in some regards than 87 octane, and while you could use it in your Toyota 4 banger, what would it be buying you?
Put another way, without a chronograph, if I were to spray paint a pair of "high end" limbs and a decent pair of more entry level stuff, how many people would be able to tell the difference?
As a counter point, the placebo effect is quite real, and if that's what it takes to allow someone to shoot better, then the extra dollars might actually be worth it. Heck, marketers depend on it.
