Reproducibility was as I recall quite good.

But I suspect the forces involved in lobbing watermelons scores of
yards swamps the characteristics of the load -- so variations
would appear as "noise".  Imagine how the same (scale) mechanism
might vary with a load like a tennis ball (over those distances).

 One other thought you might be able to buy a tennis practice serve machine off the shelf with high reproducibility.

I would think that would put way too much force into the "throw" (?)
I'd played with things like "Nerf guns" figuring they are tuned for
low mass projectiles (I suspect increasing mass just makes the problem
harder to solve):

"Lob" is a great choice of word to describe my goal.  All I want to
do is move a mass to a particular location over a trajectory that
ensures it won't interact with anything along the way (hence a HIGH
lob).
Ideally, I would like the mass to STOP at the destination (not bounce
or roll away) but that's a secondary goal.
[That;s what led me to beanbags and water balloons]
