For timestamps and completion time of each stage, check the video description. Pinning this comment to expand on that since I'm over the description page's character limit... I uploaded this video of my 'personal best' replays right after getting S-rank on all stages. Most of them were completed by finishing them in JUST enough time to get the highest rank, so I thought it might be helpful to those who are trying to complete them by giving an idea for the maximum amount of time spent on each level in order to get S-rank. There are some exceptions where I got them with one or more seconds to spare (Mario Master, Death Mountain Duel, Beneath the Hollow Tree, Escape Expert, Motocross Maestro, Balloon Basher, Neigh Slayer, Firefight, Walloping Wispy Woods, and Eye in the Sky are only ones I know as of now) but the rest of them I believe were finished one second apart from an A rank. The only one I completed VERY quickly was Firefight from Zelda II. If anyone has beaten that time, I'd like to see how you did it.
