Ok so there's all 4 possible no glitch laps, now you can ponder these for a few days and figure out what is optimal on your own, or wait for me to explain it to you :)

When you enter a cannon, the game manually updates you position along a set path at a given speed determined by the cannon setting. In this case, your speed in the cannon turns out to be about 500. Whenever you exit a cannon, your speed must be returned to what it was before you entered it, so whatever action was occurring on the final frame before entering is applied to the frame you exit.
In the case of a low cannon, this happens because you graze a wall upon entering the cannon, and then experience the speed loss upon exiting it. Since wall hit speed losses are dependent on your angle relative to the wall, the more extreme the angle, the more extreme the speed loss.
So, what should be impossible under normal circumstances, if you hit a wall and lose almost all your speed upon entering a cannon, you will end up with negative speed exiting it. This should be impossible since if you drop to almost 0 speed and are facing towards a wall rather than the cannon trigger, you wont be able to enter the cannon.
Enter supergrinding. By supergrinding into a wall you can achieve the same angle you need for a 0 speed wall hit but have EV left over to bring you into the cannon on the following frame. This unfortunately comes with the caveat that the external velocity you use to get into the cannon is also considered in the speed loss on the final frame, and so you just end up with a regular low cannon.
By some stroke of luck, there is a way around this. For whatever reason, if you enter a cannon mid-air, your external velocity is NOT considered (presumably if you were to be accelerating in a fall, it wouldnt all of a sudden hurdle you out of the cannon on the other end with increased speed), so as long as you are in the air when performing a 0 speed wall hit with momentum directed towards the cannon, you will exit the cannon with negative speed.
But how much negative speed? Well, Nintendo wanted to ensure you wouldnt exit the cannon with more speed than usual, and wanted the higher speeds still retained a somewhat equal amount of speed exiting the cannon, so they used what looks like a negative inverse exponential with a linear asymptote to determine cannon exiting speed. As you might expect, this breaks down quickly when you traverse into negative speeds, and we end up with about -560 IV. Wait, IV?
Normally, velocity is capped at 120, however in the transition between cannon speed and exiting speed, there needs to be a grace period where this does not exist to make it look smoother (unlike when you enter the cannon). This grace period starts the instant the cannon is triggered, and ends when your airtime resets to 0, since there is no guarantee you will reach any point in the exact same amount of time.
So, we exit the cannon with this -560 IV and get shot immediately backwards, with enough speed to not only pass through the cannon exit wall in a single frame, but fly across to where KCP2 is located, skipping the entire post-cannon section.
As an extra note, you can only enter a new checkpoint if you exit the one youre currently in or adjacent to. This means we actually drive backwards over the cannon checkponts until we exit them, jump straight into CP23, and enter KCP2.

This TAS is obsolete, please see the improvement here: https://youtu.be/8qo_2rebZYo
This is a tool-assisted speedrun (TAS). Played on SwareJonges Dolphin 5.0 LUA Core v3.5. Tools used: slow-down, savestates, frame advance, TAS input, TAS code, and RAM watch (info display).
TAS BKT Cut: N/A
Previous BKT: N/A
RTA BKT (46.441 by Kasey): No video
Music: Luigi Circuit - Mario Kart Wii (yup)
Made this to take a break before I get into things I really dont want to have to do. This is about as optimised as the rBC 200cc TAS, however took less time due to the run being shorter. Would actually be surprised if sub 46 was possible.
