Baum harris recognition is fast if you are exactly at the reference angle, but it is really bad to auf before zbll, imagine U2 recognize zbll and U2 again to solve the case.
Do you know 2 sided recognition for all algorithms or just auf to find the patterns you know
follow the scrambles on cstimer or just hand scramble?
less time consuming(you can do much more solves in one session)
you cannot scramble the cube exactly the same all the time, which is good
