I hit a 350ft no wind HR off a tee with BBCOR bat, but Zepp says my bat impact speed is 52mph, with a max of 60mph. Weird? I only swung 70mph with a BESR so I think it's accurate.
Something is amiss there. Not a physical possibility to hit a ball 350 feet with a barrel speed of 52mph. I suspect poor performance by the zepp.
