v... the actual speed of the supergrind
x... max speed of the vehicle without wheelie/boost (84 kmh Funky Bowser Bike)
y... side speed gained by supergrinding towards a side (can approx be found with som when going very slow and releasing super grind with a bounce and then turning in air will increas the som speed towards the value of y !not exact!

alpha is the angle which you are facing the ground with during super grind

due to MKW physics probably not being equal to our physics this may not be 100% exact but it's the closest I was able to get during a short maths session

If anyone is interested in how I made the formula feel free to let me know.

Meaning the SOM actually will display the SUPERGRIND SPEED itself aka sideways momentum?? Holy shit. shroom speed is 120, whats the speed for that? and how did you find the forumla?

Does anyone know the displayed SOM value during super grinding? does it exceed 120?

Sorry, I meant to say the actual value of the speed, not what's displayed. Therefore, the vid doesn't help, but I blame myself for phrasing the q poorly.....check out Black's definitions of v, x, and y in the OP.

Why does it not just fluctuate between 83 and 84? Sometime's it's 82 or something else. Human error?..(the TAS is shit) or is it just a nuance of supergrinding? Also, that turn while supergrinding probably could have been taken tighter maybe? Could it have?

Why aren't there other tracks using super grinding in TAS, like maybe MC, CM
's straight, or the straight on KC or something else like that?
