Just starting with SP Lite
I just got a SP Lite.
I took a bunch of balls and gave them a pressure test by hand. About 10% discarded as too soft, 60% soft (would not play with), 30% high pressure similar to new. Fuzz and diameter were not used to select, only the hand pressure test. I'm using only the 30% with highest pressure.
I am experimenting to learn to operate the SP Lite machine as reproducibly as possible. So far I find that some setting combinations are more reproducible than others. I want very low speed to grove better ball watching habits. With elevation angle, spin, court bounce point, as well as pace there are a lot of parameters. Also, I find that the pace setting control knob is very sensitive, 4.0 to 4.3 increases pace quite a bit. With one elevation setting under 4 might not clear the net and above 4.4 is too heavy. Only a few secessions so far.
