Latest swing videos (filmed yesterday morning, just sent to evolvr just now). I haven't made any changes from @Grizvok's video, but I do occasionally make a few swings with that arm change. I am definitely doing what is described there as the amateur style (also, you're a better public speaker than you give yourself credit for).
I am just starting this challenge and curios, is there an issue if I look back at my scores and record shots retroactively to the start of this season? Fortunately I have every round in GamGolf so I can find the scores. Worst case, I can just start from here.
