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.
