[TAS] New Super Mario Bros. 2-T 100% Shell

In the previous and next stages (2-4, 2-5), Shell is overwhelmingly faster than Fire, but I was wondering how long it would take to run 2-T in Shell.
As a result, the In-game timer is 2114, 46F faster than the Fire on Suuper's video.

I'm surprised that Shell is faster than Fire than I imagined.

Can anyone explain how he manages to jump (?) while midair

[@johnr5985]

If you jump when in the shell and get out of it on the frame when your vertical velocity is exactly zero, Mario will jump automatically.
