Also, taking a look at these algorithms, I don’t think they are any easier than drew/Lucas parity algorithms.It probably cannot get any easier than something like these:
Uw'
m F
U' 2R' U F2
U' 2R' U F2
U' 2R' U F2
U' 2R' U F2
U' 2R' U F2
F m'
Uw

Uw L' R
L' U' 2R U L U2
L' U' 2R U L U2
L' U' 2R U L U2
L' U' 2R U L U2
L' U' 2R U L U2
U2
L R' Uw'

Uw' L' R
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
U2

They are just (2R U2)4 2R with 1-2 setup moves around the 2R move.
(2R U2)4 2R
=
2R U2
2R U2
2R U2
2R U2
2R
=
2R U2
2R U2
2R U2
2R U2
2R U2
U2
So if you add, say, the setup moves R2 U' before every 2R and undo with U R2, you get:
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
U2
And then do a few conjugates to make a single dedge flip:
Uw' L' R
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
R2 U' 2R U R2 U2
U2
L R' Uw
It's possible that the entire sequence is what's repeated except for one move, but it's nastier.
(2L' B2 2L B2 U2 F2 D2 2L D2 F2)4 2R'
And it's possible that all of the moves of the alg are the result of a repeated sequence, but those can be very long:
(3Uw' Rw2 3Uw2 Rw2 3Uw2 Rw 3Uw2 Rw' 3Uw2 Rw)15
And even longer if the sequence that is repeated is shorter!
(3Uw' Rw2 3Uw Rw 3Uw' Rw' 3Uw2 Rw)585

EDIT:
If you happen to know the PLL parity algorithm: 2R2 F2 U2 2R2 U2 F2 2R2
Then if you make the middle move a quarter turn, a very easy alg to remember can be made from it also:
- Do the first bit: 2R2 F2 U2 2R U2 F2 2R2
- Do the move F2: 2R2 F2 U2 2R U2 F2 2R2 (F2)
- Do the sequence to swap two adjacent centers (like in reduction):
2R2 F2 U2 2R U2 F2 2R2 (F2)(2L' U2 2L 2R U2 2R')
- Do the obvious finishing move (F2) and then add two setup moves (the same setup moves as those in first algs listed in this post).
(Rw' s) 2R2 F2 U2 2R U2 F2 2R2 (F2)(2L' U2 2L 2R U2 2R')(F2) (s' Rw)
But that's all I've got.
