Zeroing: This is obviously a joke, but "Zeroing" is also is what I like the to call RUD comm/OLS last slot magic that Feliks used to do sometimes (e.g.

Snyder3: Tony Snyder once stated that he is working on
the best method ever, which will supposedly be what everyone uses in the future, promising godly ergonomics, insanely fast times and average movecounts in the 30s. Obviously, this method doesn't actually exist.
HK: A method inspired by an April 1st video made by The Cubicle, which is actually not terrible for speedsolving. You start off by building a pEOArrow, then a DougLi block, HKOLL and HKPLL
CFTOP: Cross, F2L, T perm, OLL, PLL: The best method ever, used by Tymon and Tao Yu. Proven to be sub 7-able.
OrtegaZB: No idea, sorry.
The Franciscos: IIRC, you solve first layer minus a certain amount of edges and corners, depending on the method. Then, you do the second layer, and finish off LL+whatever pieces were left unsolved in the first step (again, depending on which of the 3 methods you do).
CDLSS: No idea #2
CFOP: No explanation needed
TICT: ???
Bob Burton: I feel like if you actually use his algs, it would look like you're doing a different method.
