Oh my! Would your really do that during a speedsolve or did you find it somewhere?
Because there must be like hundreds of cases like that and if I had to know the most efficient way to do every one of them I think I'd go crazy.
I found this when looking for a case for ZZ F2L (the other pair that that alg solves). I never remember to use it in solves though. There almost certainly are many more good algs that aren't obvious at all that not many people know about - we need to keep looking!
