I had around 2.3 average, 1.8 single earlier, with right index S move, left index U, reset left index, left index f'.Edit: also what speed are you getting on the alg? I’m getting around 1.2 at the moment.
Your execution is what I meant by the left-index S move, and it seems to flow okay, but my left-index S moves are really inconsistent. Not really in the mood to drill algs now but I'll try timing with this execution later.
edit: Got around 2.0-2.1 averages with both executions. No clear winner yet. Also, I'll still have to use the RUF alg for big cubes, anyway.
