They both seem entirely legit. I attempted to contact someone who knows the player to get permission to add the runs to the site, and to find out whether they were done on an actual bike, or via MAME. Site rules say that a top time can generally be listed without permission. Does anyone have any objection or point of order to raise about the validity of these runs besides the method?

Did anyone who has a time on the leaderboard do it with an actual bike? I would greatly value any feedback on whether that makes it a bit easier to react on such a fine level as you see above without shintysix squillion resets.

I have already added plenty of runs on other leaderboards (OutRun, for example). I don't want to be "first" or "second" when there's five runs faster than mine.

There are speedruns on Nicovideo too, like this one

In general I absolutely agree with you, but since I've only been playing Arcade for a week or less I wanted to double-check in case you guys saw anything odd about it. I was able to get Anthopants to submit his Expert run from a similar Youtube trawl. Unsure whether you understand Japanese but would you be interested/willing to search nicovideo for anything else that we could add here, to upright or limited or ride-on?
