It’s interesting, the different algorithms these monitors use to estimate distance. Because they certainly aren’t measuring where the ball actually hits. (Speaking of the PRGR/SC200-300/Mevo brood only, of course. Trackman probably could register actual downrange impact…)
Anyway, as I’ve written before here, ball speed is the only measurement from mine that I put a lot of credence in, and 157-161 ball speed does not sniff 300 carry on my gadget. Though the 265-270 it does allow me, is certainly acceptable. Personally, for @kenk’s question, just practicing with the monitor in ‘swing speed mode’, with a bare tee for focusing my impact, did wonders for improving chs. Basically a more quantitative version of the, listen for the whoosh! drill. And then try various movements and see what those do to the speed readings. (While still hitting the tee.) Mix in divot board work (obv not with the driver) and try to combine big speed with ideal divot patterns. I
I’d try superspeed if I’d the cash and time. New job is taking up a lot of the latter.
