Obviously he has a chance to get the world record. That's the case UWR or not. The problem is you pointing out something completely irrelevant to the thread. It's not the first time Seb's records are low key belittled by fankids of more popular cubers. Your location really isn't helping your...
Everything reduces to a different case until you only have a sledge/hedge left. There are like 5 different things you need to learn and then you just put an adjacent center in front and you're all set.
Optimal solution length is not a good indicator of the difficulty of a scramble with a speedsolving method. EO and blocks are much better, but have fun quantifying them in a fair way. Or, you know, just look at the time instead of trying to fix a problem that doesn't even exist.
tbh your timer stop was probably bad. Most judges just don't call them, because it's hard to tell for sure unless it's super blatant. Not sure what a delegate could've done for you unless you could show video evidence.
World class 2x2 solvers can 1-look a solution at least as fast as it takes world class blders to memo. Conventional bld methods are objectively garbage for 2bld. They have no advantage over speedsolving methods.
