1. What's the difference between Glitchless and Glitched catagories respectively?
2. What is considered the 'first visible frame of the last Mystery Box being opened at the end of the run'?
3. What's the difference between 1/3/5 Mystery Boxes catagories?

Long story short, I haven't been speedrunning in a while. I booted up a game of SS and decided to go for the 5000 Coins category; I managed to get a sub 10 minute run by sheer luck, but I didn't record my previous attempt nor my next attempt after my run.

Will my run get instantly rejected or are there exceptions to this?

Just out of curiosity
