20 is possible from this with a very long extension into some double slice but ew

I found this DR at >45 mins, after checking my main bunch I only had useless DRs and I had to write down some desperate extensions to try to save the attempt

It's possible to get 19 from this start with some RLFB shifting but I whatever
