I started learning the soroban (Japanese abacus) 2 years ago because I wanted to understand how people used it to perform calculation feats. I spent a year practicing using the abacus mechanics, and another year replacing the physical abacus with a mental abacus, so I can operate it all in my mind.
So here's some analysis of my progress. My results aren't impressive, but cultivating the mental abacus has been quite interesting!

yikes! do you have javascript blockers? The site is unusable without javascript.
FWIW, it's a custom rerender of https://github.com/whacked/cow/blob/main/learning%20soroban%...
It's loading fine now. No blockers.
