Adding a purist mode category could be a good idea to add that extra challenge.

I vote yes.

I think Liftoff changed some of the official tracks for Liftoff Arena. I believe the Dover International and Formula FPV tracks are no longer part of the official tracks.

I think the first six are correct, but the 7th track, called Round and Round, is not listed on the track list on the site here... but the old tracks are.

Here is a link to the fastest setup I use for all track records. https://steamcommunity.com/sharedfiles/filedetails/?id=2893952812

FYI, this frame and components are slightly lighter than others that report the same top speed in the menu. This drone is actually the fastest in my experience. Also, Liftoff has an interesting behavior where you can reach speeds of ~250 if you make a coordinated turn. I frequently try to take as many turns on a track in such a way whenever it makes sense to gain the increased speed.
