If the range of it is iffy, you range it or pass the shot.
I have one recurve that was built when I was 2 years old and probably gives me about #44-#45 net, and the only thing that stands between me and killing an Elk with it is ME. Well, that and the fact that I own 3 longbows and a pair of recurves that get me between high forties and low sixties that I would use first ;)
Point being, if you can’t kill whatever you’re hunting with the bow that you’ve got, that’s a You Problem.

Anything else is just a WAG.... or a marketing claim.
And let’s say you DO shoot through a chrono; then what? You might know your velocity at 2 yards, but what is it a 20 or 30 or 40??
Good quality bullets are as uniform as they can possibly be, so you can use a ballistics program to predict where they will hit; arrows (from one shooter to the next) are just not that uniform, so they slow down at their own, unique rates and the only way you can know where YOU are going to hit at X yards is to spend a lot of time shooting at X yards....
Which doesn’t cost a nickel unless you lose or destroy a lot of arrows that way. God knows I do.... ;)
