Recorded at Open Sauce 2025 with kind time and support from creators Aden Hurd and Matthew Patrohay (who created Purdubik's Cube with Junpei Ota and Alex Berta).

The setup only allowed for a limited angle of view, so I made a lot of extra moves did some very sub-optimal stuff (e.g. swapped edges in cross). So I didn't quite beat my 20.29 from 2021 (youtube.com/watch?v=2YOt0xcFuqA), and sub-20 will have to wait for another day.

Reconstruction of the 20.53:
