unfortunately there is none. most are about the same length.
but i recently found a weird way to parity
first i put the two parity edges in the DL and DB slots and do
1,0 / 0,-1 / 0,-3 / 5,0 / -5,0 / 0,3 / 0,1 / 5,0
that switchs UF-UB DB-DR
then i do this alg to switch UF-UB DF-DB
1,0 / 5,-1 / -5,1 / 5,0
it end up being just as long as all the other parity algs, but since both start for 3 or 2 then go backwards
it ends up being way easer to remember and most of the turns are only on one layer so you dont have to align both layer as often
plus they are both good algs to learn anyway for special cases. lol
i havnt fully learned my s1 yet, but i figured this out just playing around.
anyone else do it this way?
or think its a good/better way?
