this was the official one:
R' U' F D2 F2 L2 F2 U2 R' B2 F2 R' B' R B' F' D U B2 R' F D R' U' F

(nice pattern to start, but only 3 managed a 23 yesterday)

solution (Click to View)

(U' F' U') // 3/3 222
(B D U' B U) // 5/8 223
(D' R D2 R') // 4/12 EO to a pseudo-F2L-1
B2 D2 B D2 B' D2 // 6/18 L3C
ssf: B2 D2 B D2 B' D2 R * D2 R' D U' B' U D' B' U F U
* R' B R F' R' B' R F // 8-2/24
solution: B2 D2 B D2 B' D2 B R F' R' B' R F D2 R' D U' B' U D' B' U F U

Had an L5C in 21 right at the start on the inverse (with this 223) and tried a lot of things - and as the very last thing before looking for insertions on the 21 I checked this EO 

Had 24s only twice in-limit unofficial till now
