I have to agree with the mock shaves, and the fact that you seem to be shaving "goofy footed" (to borrow a skating term). My "mock shave" was with a Fromm hair shaper with the guard removed, which I borrowed from the wife's bag of tools left over from her cosmetology school days. The replaceable blade was dull, and the whole experience was awkward because I didn't have the muscle memory yet.
Don't worry, you'll get there! I'm a year in, with my slow beard growth bringing my shave count estimate to around the "100 shaves" they talk about. It's been a blast! Just give it some time, and you will get very comfortable, & a but confident with your shaving.
I don't explicitly condone anyone attempting it, but I shaved blindfolded two months ago.

Btw, it's a "single take" video, so feel free to skip past the first several minutes where I wrestle with the practice strop I used as a blindfold :nj.
