Since the Switch runs at 60 FPS, it loses about a second over a full run. Since I've gotten into the Sub 5:02 range, the decimals finally show. If anyone knows where a final time speadsheet for 60 FPS Consoles is, that would be very useful.

I didn't realize this when I started speedruning SMB1. However, I have learned that the Switch version runs at a slower framerate than an NES or Emulator. After comparing one of my runs that died to bowser on 5:04 pace, I figured out approximately what my time would have been. At least to my knowledge, I was even with a 4:59 I found until 4-2, where I lost a framerule. In 8-1, I lost 2 framerules, and in 8-2, lost 1 more . That puts my run that died to bowser on mid 5:01 pace. In 8-3 and 8-4, no time is lost or gained. That puts my run around 5:01.5, when if it finished it would have been much slower. Is it allowed to adjust my time on the Switch to cancel out the slower FPS? I'm by no means an expert at this game, so it's definitely possible that this is very wrong.
