I am so confused with this thing. Nothing seems to be adding up. Another session with 8i and 7i. My swing speeds are pretty much identical for both clubs. R10 ing my 8i going 123yds 7i going 135yds. Swing speeds are 75 78. On the course I hit my 8i 140, 7i 150. I've tried different distances from ball to net and ball R10. Everything just seems to be off. I also calibrated it last night. ♂️ Any ideas? Seems I've tried it all.
