But, see, that's just what the [take your pick of religious authorities] said when I told him I didn't believe in [take your pick of miraculous religious events]...
And, anyway, how can I "rest assured" of anything? That's the whole point of approaching this with an open mind. If I "rest assured that it's me", that doesn't sound like an open mind...
I intend to begin my video documentation by demonstrating my own level of mastery of the fundamentals...
I say that, because unless you are an elite player, you will have stroke issues. Which means that even though you did line up perfectly, you will still miss some shots because of your stroke.
Sometimes I will miss a shot in practice, and then set it back up and miss it again, and again. Then, I go back to manual CTE and am very careful on my stroke. Yep, the ball drops right in. The previous misses weren't the system, they were me.
