The average number of turns for the algs given here is ~11.14.
Plus the 1.5 for the AUFs before and after the ELL alg, this LL method averages <24
speed optimized (with no rotations and factoring in those skip chances).
Note that some of these algs may leave off the end U/U'/U2.
ELL has 29 cases separated by the what edges are flipped into 4 groups.
The EPLL cases have an average of 7 1/2 turns
The Adjacent two flip cases have an average of 10 11/12 turns
The Opposite two flip cases have an average of 12 1/2 turns
The Four flip cases have an average of 12 2/5 turns
