Agreed. I do believe though, that the ezv site and Garmin xero are actually both shortcuts to Speed/trajectory and Range estimation and help tremendously when it comes to heavy arrows. It takes a bunch of work to learn and set them up, but once you dial them in for your bow poundage/arrow weight/trajectory, they eliminate range estimation and automatically calculate trajectory. I've never had an issue hitting at or near the right spot when meat hunting, but when the 150+ walks in front me, I like using all the advantage I can, especially as I increase arrow weight dramatically.
