The whole problem with method comparison is there isn't a fair comparison in so many different ways. Many methods have never been properly explored with modern cubes. Let's use an example.
At the 1982 World Championships, CFOP was poorly developed, and the couple of CFOP competitors were defeated by Minh Thai who was a corners first solver. Corners first then was evolved into Waterman by Marc Waterman and his friends, soon Waterman had a method with 400+ algorithms and had registered a 17.70 average at a small competition in 1987. He retires from cubing around 1990. Fast forward to the 2003 World Championships. CFOP has now been refined and developed for 20 years, but the cubes are the same ones as from the 1980's. Almost everyone at the 2003 championships was using CFOP, and the average to beat was Waterman's 17.70 with his advanced corners first method. Nobody even came close and the winning average was 20.00 seconds by Dan Knights. Shortly after the 2003 World championships, modern speed cubes were developed, making all comparisons to Waterman's 1980's solves meaningless.
Even Waterman himself forgot almost all the algorithms of his method shortly after he stopped cubing. People often say his method has 120 algorithms (after they read the PDF), but they don't understand that the algorithms in the PDF are the base algorithms and you need to introduce 3 variants for each algorithm based on different cases.
No one since Waterman has learned the full set. The closest has been Somerandomkidmike here on this forum (no longer active), who started as a 19.5 second CFOP solver, switched to Waterman and dropped to 14 seconds in a few months despite knowing less than half of the algorithms. This is not surprising since Waterman uses 40-45 moves per solve instead of 50-64 for CFOP. Today it is mostly forgotten and people just assume that since all the records are with CFOP and the only other quick times are Roux and ZZ, that this means these are the only fast methods.
I have been developing the LMCF method but adding more and more of Waterman's tricks and gradually the method seems to be migrating into a Waterman hybrid.
