A rare case where I find any non DR stuff, let alone a similar amount of DR and non DR stuff

I also had this 10 to 5C which I tried to insert but couldn't find a nice enough first insertion to continue - L (R' D2 F , D2 R' F D' F' D')

Best DR's were 9+3 and 10+3 which were (R' D2 U F D2 F2 D2 L' U) and (L2 U' B' L) U D' R' F2 D2 R. I think the latter had sub 21 potential if I spent more than 1-2 mins looking at it :P

4C4 is typically a very bad HTR subset, but in this case it worked out (piece location meant short NISS HTR's were possible, and it's a 10 move DR on a hard scramble)

Bad safety from 11+2q
