I don't know if everyone thinks the same way, but personally I am more forgiving on execution mistakes than planning mistakes. Most people might be the opposite since execution mistakes look worse. But my rationale is: if a run is rejected because the runner doesn't know certain things they ought to, that's not so bad since the runner can just learn those things and redo it. It shouldn't be that hard. They have the ability.
But on the other hand, if a run is rejected for execution, the runner might think "this is BS, this is as good as I can play. what do these people expect, I quit." For planning rejections, the runner will realize "well, if I had tried to get some feedback before submitting this run, people could have told me about these shortcuts" and feel like the rejection is at least partially on them.
So I respect the last post but personally (not as someone involved with SDA) I really disagree.
I can certainly see your point. I think this is where services such as Youtube come in handy, where you can show your run to anyone who will watch, unofficial verifiers if you will, and someone here or there can tell you if you've missed one thing or another. I just think it can get really demoralizing for someone if they've submitted their best efforts, and it still isn't good enough because of some planning issues. I could understand it if better planning would lead to like over half an hour of improvements, but if it's something about a couple boss fights and a minor route change or something along those lines that might only save 4-5 minutes tops (depending on run length and whether it's segmented or not, obviously), then I'm not sure I can justify a rejection.
Thankfully, it won't be an issue here since the runner said they will redo the run. Again, though, I do see your points and for the most part I can agree with them. Only to a certain limit on forgiving the execution mistakes, though - if someone's play quality is obviously crap, I wouldn't want to watch that run, although I'm quite sure you agree that you'd only accept execution limits to a certain limit.
