Because you're not able to see the logic of pinpointing some faulty mechanism that might be giving trouble to some less skilled player doesn't make it silly. If it doesn't help you or you cannot/don't want to contribute, move along.
Many of us have given advice and helped out for a while now. It has been largely refused. Not by everyone, but by a lot. That's why video documenting that it's not difficult if you prepare was necessary.
And when that was done, some folks try to move the goal posts instead of admitting there may be something they can improve on.
That's silly.
