yeah okay just over 3 hours but you know what this proves? It proves that it can work for any cubiodal rubiks cube(including perfect cubes) to do LBL. I say cuboidal rubiks cube because a lot of people consider things like Skewb octahedron, Pyraminx, Megaminx and all its sizes, and the icosohedron rubiks cubes since they follow the same principles as the perfect cubes.
