Excepting the 10 degree change and one meter loss. You'd have to know the release speed for a 1 meter outcome.
But, yes, and I suppose that is my point, that if most folks, say, were going to punch a hole in a wall, they'd likely strike the wall with their fist roughly horizontal to the shoulder.
Horizontal. Mechanical advantage.
For a shot putter, certainly a spinner, I suppose if we just measured the release speed alone, that the greatest measurements would occur for a horizontal release, very low anyway. For gliders, the motion low out of the back, the drive into delivery imparts a bit of a ramping up of the shot, less horizontal.
So, anyway, we know for sure that there is a great loss chasing maximum release speed at all costs (no attention, at all to release angle), so the angles of great and optimal throws increase.
The one article says 37 to 38 degrees and that seems spot on to me, well down from the inarguable optimal 45 degrees for equal take-off and landing equivalent heights, way off even the 42 degrees or so for the parabolas where the release height is 2 meters above the landing height like common to shot putters.
So, my point is simply that now living with one's mechanical limitations, being what they are from this guy to that guy, that for whatever "groove" best suits you, the higher the release angle, the greater the reliance becomes on strength, the less important the gross bulk (mass) of the thrower.
Forget about 1 meter differences; big events are often won by single centimeters. It's worth a coach and an athlete finding the sweet spot.
Proof: At a world class typical shot release speed of 14 mps, but thrown vertically straight overhead, the shot will travel roughly 10 meters above the release height. If a 150 lbs. man can create that release speed, a 300 lbs. man has no advantage over him via his mass advantage. Whoever can create the greatest release speed, now more of a strength thing, wins.
The little guy literally has the weight of the world backing him up.
But, if you need one of these guys to help you push your car across a parking lot the quickest, pick the fat dude.

I meant to add that I think Nuno, Tony, Donk, I, and others are on the same page here . . . just talking about the finer points of some of the physics of throwing.
If you have a kid who is throwing way flat, turn on a water hose, have him hold it at release height and move the angle up and down to find the point the water squirts the farthest (it'll be 42 degrees or so), then, once he "sees" the effects of angles, help him find his best angle. br
