struggle on this JZP for 20 minutes. it has so many variations and paths to HTR.

this scramble's 16 can be foundable?

the best DR found on this scramble were this 11+2 and its variations. got the solution using a block builidng start on HTR

Fast and linear solution

D2 R' U D B2 U' D' L' //HTR 8/17
D2 B2 //L2E2E 2/19

there was a direct insertion after the last move which cancelled 5 resulted in 22:
B2 D2 L2 F2 U2 F2 L2 D2

then you could notice the final move in inverse didn't affect the 2E2E and inserted in # to cancel 7!
