R' F2 L U2 F2 R' D2 F2// 16 to 2e2e3e. Could've done a 6 mover at the end here, didn't cancel enough.

* = D2 B2 R' D2 F2 U2 L' F2 //(8-8) to 2e2e. There are twelve 8-move algs for this exact same case that I know of so I was lucky to get this.

** = B2 U2 L' F2 U2 B2 R' D2 // (8-4) I know of only four 8-move algs for this case so it doesn't take long to check them all, nothing too major here.

:) = S2. I learned this technique from the new DR guide. Check it out, cancel moves for free.

Final: F' R' D2 B2 R' D2 R' D2 B R2 L2 F2 U2 L' F2 U2 B2 U R2 (19)

[After 1 hour: If I had inserted M2 at R2 L2 and before the last B2 I could've done an easy M2 U2 M2 U2 insert that would've left a final 18 solution. Chong Wen would be disappointed in me lmao]
