The solution I provided was what I found afterwards. I was playing around with it until I found some ridiculous skip or something. On your note, however, I have been trying to simplify my solutions, work on lookahead, etcI got a 5.74 first try
here’s my solution
some tips I suggest for your solves:y // inspection
F’ R’ D R2 L’ U L’ // xcross + planned free pair
U L U’ L’ // second pair
y’ U’ L U’ L’ // third pair
U R U R’ // fourth pair
F R U R’ U’ S R U R’ U’ f’ // OLL
U F R U’ R’ U’ R U R’ F’ R U R’ U’ R’ F R F’ U2 // PLL
49 moves
my time could have been a lot faster but my hands are tired after a day of practice so I fumbled the fourth pair
for the third pair, you can just do a y and then solve the green-orange pair. It’s a lot better than what you did because it doesn’t undo the pair that you did (which is what happened in your solution) and doesn’t require a y2. I suggest doing solutions that are simpler. Basically, don’t try to be Tymon.
As for your solution, it's quite late so I don't have my cube and alg.cubing.net isn't working for some reason but the amount of free pairs is absurd
