I got about halfway through the weekly comp scramble then ran out of time. Suggestions?

D B2 D' R2 D2 B2 U' B2 F2 D2 L2 R' D' U' R' F2 D B R2 D L'

Premove L
B2 D F' D' F R F' //2x2x2 (7/7)
L2 B2 L2 U B U' B //F2L-1 (7/14)
//My last minute thing was U' R B' R' B U B U' B' U which led to AB5C but then I gave up because of time.

I would just do F U R U' R' F' to leave 4 corners. (after 21 moves)
or change the F2L-1 step to: L2 B2 L2 U B U2 R B' R' B U B which leaves 5 corners (after 20 moves)
This is what I found now, but there could easily be something better.

Edit: IF says 32 for the L4C and 31 for the L5C.

WR-potential scramble from Sapporo Open 2014.

Scramble: U2 F2 U2 F' L2 U2 B' U2 B' D' R D B R' U2 F2 D' F2

I really hope you FMC guys try this scramble before I write my solution here.
Unfortunately I couldn't break WR.
24-move solution in 15 min, 21-move solution in 30 min, and no better solution was found in the remaining time. :(

Solution: U2 R U R' D R U' B R2 L' B' R' B R2 L D' F D F' R L2 (21 moves)

Here is 15 min backup solution. (24 moves)

(Inverse)
Pre-scramble: U2 D'

2x2x2 block: L2 B'
F2L minus 1 slot: L R F' R' * F L'
Finish F2L: F' R' F
All but 3 corners: R2 U R F R' F' U'
Correction: U2 D'

Insert at *: R F2 R' B' R F2 R' B

Secondly, I found the following 21-move solution.

(Inverse)
Pre-scramble: U2 D'

Expand block: L2
Pseudo 2x2x3 block: R' F D' F' D
Pseudo F2L minus 1 slot: L' R2 B' R B L
All but 3 corners: R2 B' R'
Corner 3-cycle: R U R' D' R U' R' D
Correction: U2 D'

I still continued to search other solutions in the remaining time, but I couldn't find any better solution.
NB: jpbrc's solution is different from mine, although jpbrc's one seems more natural.

The best I could find in one hour was a 22
On inverse with premove U2:
L2 B' R' F D'
F' R2 D R D' R (all but 4 corners in 12)

Skeleton for normal scramble and insertions:
U2 R' D R' * D' R2 F D F' + R B L2
+ = B L2 B' R B L2 B' R'
* = L' B L F2 L' B' L F2

Can you post your solution (in spoiler if you prefer)?

It was an amazing solving process, and congatz on both single and average PBs!
Now I beat you in only mega avg, which is not my main event.
Since I'm not bad at SQ1 and FMC, it is really respectable for you to beat me in both events, and I'm trying to practice another event as long as won't beat me next time:p.

Thanks! I think I will improve my Megaminx average since I'd like to have a better sum of ranks, but you could learn BLD and get decent, I don't see myself getting very good at that.

EDIT: The LL looked cool so I looked up the optimal alg: L U L' F' L U' L2 U L F. Is this a popular 1LLL case?

Tips? Currently working on insertions and alternative LL methods.
