As most people in this thread have said, how?
EOCross=FB+DR (4 pieces plus EO of everything else vs 6 pieces is pretty fair, similar number of moves, ~9 for each).
2.5 ZZ pairs=rest of second block (ZZ pairs are very fast (imagine CFOP pairs but faster) and Roux SB has some bad blind spots as well as some overturning issues).
Finish F2L=CMLL (this is like a 1 second alg vs a .6 second alg for LS and about .3 for half of other pair, so is in ZZ's favour mildly).
ZBLL=LSE (both are about sub 2 and could be substantialy faster depending on the case, even when factoring in using OCLL/PLL instead).
Also, that video doesn't have these:
