Thanks to jellyfishswimmer for building a killplane viewer. Thanks as well to Dage4 for presenting me with an image, using said viewer, of the killplane gap abused in this video.
I can not believe this is real.
In order to orient my gravity, I had to preform two mid air gravity shifts, by dropping the hypotenuse of Shadow's relative vertical and relative horizontal speeds below a value of 5 for 1-3 frames, and then exceeding that value. I also use a short pause hover to increase positive relative vertical speed in order to take a "straighter" path, while still maintaining a that value above 5 to lock gravity.

This is a tool-assisted speedrun of Sonic Adventure 2s Metal Harbor (Mission 3), with a completion time of 0:19.94.

This TAS does not use a speedglitch that exploits repeatedly bouncing to build speed. Personally I think this game is a lot more fun without using this tech, and it much more closely resembles non-TAS play.
The current record using TAS Bounce is a 0:14.17 by me:

I never would have imagined sub 20 was actually possible on this stage, every little innovation mattered in achieving this time. Brianpso reminded me of an exploit we discovered long ago, to use instant turnaround (a glitch letting you flip 180 degrees and convert positive speed into negative) to decrease deceleration, because decel works differently when Sonic is moving backwards. This allowed me to shave off 3 frames on the first platform in the stage.
Shier optimization was not enough to achieve sub 20, we needed innovation. Following the second jumppad, I used the downhill to build speed rolling, and then excited a very precise super bounce to VHC (vertical-horizontal conversion) and achieve a speed boost when converting to the flat ground. This also saved something around 3 frames.
The Carrier section utilizes the small slopes on the left and right of the main area to conserve high speeds captured by the 14-speed speedpad. Minimizing time spent on the flat ground conserved the most speed, and this zigzag path ended up being the fastest. Having extra speed at the final jump saves a substantial amount of time since aerial deceleration is so harsh, just have a bit higher starting speed equals a much sooner landing. A pause hover is used to conserve as much speed as possible.
The instant turnaround whistle at the end was just flashy entertainment, it did not lose or gain any time.
This TAS was a lot of fun to make. I have been on hiatus from TASing for a long while but perhaps there will be more Sonic Adventure 1/2 TASes from me in the near future.. Stay tuned(?)

The main time-save here over the previous TAS is the loop speed abuse after the final checkpoint, which skips a sizable portion of the last area in the stage. Unfortunately, the optimal movement for this trick requires passing through the camera trigger on the loop, which gives a not-so-entertaining view of the skip. It is possible to avoid this, and have the camera follow Shadow, but not without sacrificing frames. Sorry about that! :(")

So yeah, I did a spindash at 1:31 to let me homing attack before I land... yaaaaaay... why didnt I think of this before?
Please watch in HD if you can, it looks much smoother xD
