I just ran the numbers on your 490gr shaft setup, I'm going to assume you didn't have a peep in the bows but even if you did its an atrocious miss. a 490shaft should be moving around 282, IF the bow was actually maintaining an accurate draw length. I don't normally get too tore up over things in life, but the fact that it is widely known AND ACCEPTED that manufacturers are all mislabeling draw length settings to skew them toward the longest end of the draw length tolerance to increase consumer speed is one thing. In this case it looks like the manufacturer, again, has missed the draw length setting and still cant get within 10fps of what they're claiming their IBO rating is (ON THE SLOWER BOW) let alone the one that is suppose to be shooting 340?
I don't give a shit about speed ratings because I shoot 270fps with a hunting rig and 280 with an ASA rig, what I care about is supporting a company that's products don't need grossly inflated ratings AKA lies to sell the product. Last year was the first Elite that I've owned that had the exact same draw length issue, the only difference is it still made IBO at the setting. I wanted to own one of these bows but until more data comes out and I hope it does. I really want to be wrong in this situation, I really love how these bows shoot, I want to support mathews as I love their engineering. But in this case its no different than buying your components overseas and flying the flag on your website. Its a moral problem for me.
If anyone has more measured data, Id absolutely love to see it.
