Really happy that I found optimal from this variation hell.

I don't know why I didn't have (F B) B' L' F eo that gives 20/21 but not sure if I would've found the dr anyway

Once I got this dr and saw the blocks I finished it immediately so the rest of the attempt was just fishing for a dr with sub20 potential and it didn't show up :(

I almost missed this cause there was also another slice in 21 from this htr which was +1 and I checked it first and I got this DR at like 50min.

Quite lucky as once I got this DR I just tried a few HTRs hoping for some big RL shortenings and it spawned,
but I didn't have much else to check so I would have probably returned to this dr (and its twin) anyway.
