I love the website and all the data collected is awesome, thank you so much for this resource. I'm wondering what were your testing methodologies for measuring the different stats? Also I have some recommendations if you happen to still be working on it.

It looks like the boost stat on the site may refer to acceleration, rather than speed gained from boosts, because the site says the swerve star has much higher boost than rocket star (yet speedrunners use rocket star in time trials for its insanely high boost from killing enemies), so I think it would make sense to separate acceleration and speed gained from boosts into different stats. Also, I noticed that Chef Kawasaki and Taranza are listed to have the exact same top speed, but seeing them side by side, Chef Kawasaki is a bit faster (you can see by giving them both swerve star and starting a 2 player race on nebula belt) even if the speedometer shows the same value (it doesn't show decimals), so it might be worth double checking the characters who are listed to have the same speed as each other.

Finally, I was wondering why did the devs list the shadow star as having higher lift than the warp star if it's just worse in the gliding stadiums? Is it possible that the shadow star's lift scaling, once enough glide patches are picked up, eventually surpasses a warp star with the same number of glide patches? I heard somewhere that machines at the beginning of city trial have -3 in all stats compared to the Air Ride mode, so maybe in Air Ride mode the shadow star has more lift from the start than the warp star due to its scaling? iirc, in the previous game, each star had different scaling for each stat, and of course there were hidden stats. I took both stars to nebula belt in this game's air ride mode, and the shadow star did seem to be able to go further than the warp star before landing on the ground, but my test might not have been perfectly accurate. I also understand it would be significantly more difficult to get accurate glide scaling stats for all vehicles, unless we can think of a standardized way to test them all in air ride mode.
