Sub 20 with LBL method?

[AvGalen]

Just tried:
Cross, Corner1, Corner2, Corner3, Corner4, Edge1, Edge2, Edge3, Edge4, Edge OLL, Corner OLL, PLL (If you know it), Corner PLL, Edge PLL (for a beginner 4 look last layer)
5, (4, 3, 4, 3), (8, 8, 8, 7), (6, 7), 17 or 13 + 10
6, (4, 3, 3, 6), (7, 8, 8, 8,), (12, 8), 12 or 9 + 10
5, (3, 4, 3, 7), (8, 8, 15, 8), (6, 11), 12 or 9 + 10
5, (0, 4, 6, 3), (8, 8, 8, 8), (12, 8), 13 or 13 + 0
5, (3, 3, 5, 7), (8, 8, 7, 8), (6, 9), ?? or 9 + 9

Edges take a lot of moves, but by using keyhole I get:
7, (4, 5, 6), (4, 4, 4, 5), (7), (0 + 9), 10 or 0 + 10
7, (4, 3, 4), (3, 4, 3, 4), (7), (6 + 7), ?? or 9 + 10
7, (3, 3, 4), (3, 4, 4, 4), (8), (6 + 8), 10 or 9 + 1
6, (3, 3, 3), (4, 4, 4, 8), (7), (6 + 9), 15 or 13 + 12
6, (4, 3, 4), (3, 4, 3, 4), (8), (6 + 8), 10 or 0 + 10

CFOP:
8, (7, 7, 7, 10), (0 + 9), ?? or 9 + 9
7, (3, 8, 6, 7), (6 + 8), ?? or 9 + 12
6, (7, 3, 6, 7), (6 + 8), 11 or 9 + 10
9, (5, 7, 7, 3), (6 + 8), 16 or 13 + 12
4, (6, 8, 6, 7), (6 + 7) 13 or 0 + 13

I didn't use any shortcuts and didn't "notice" cancellations. Just the solves as I would have performed them. If I would have used (R2 U2) *3 shortcuts I could have saved some moves for the beginner solution

?? means I don't know that PLL

Yes it's possible

This guy can do sub 20 LBL F2L average.....

He even got a 9 second one!!! LBL F2L!!!!!

His LBL average is like 28 seconds!!!!

LBL (cross + 4 corners + 4 edge + EOLL + OCLL + PLL):

18.48, (17.36), 21.60, (POP), 19.33, 26.03, 29.88, 24.52, 23.72, 21.43, 18.30, 25.91 > 22.92 avg

I reckon I can do it. The first five are 19.80 avg. In the middle, I got a lot of annoying flipped edges...

Not even rolling..

 

[Lucas Garron]

Alright:
18.54, (22.93), (16.92 PLL skip), 20.98, 19.19, 19.59, 20.40, 19.58, 19.63, 18.28, 19.54, 21.43 > 19.72 avg
And after 43 solves of that Nakajima-speed twisting (lookahead is insane for LBL), my fingertips are still cold...
(SD: 0.99)

EDIT: 17.87, 18.10, (22.30), 17.42, (15.89) > 17.80 avg5
I don't think the 15.89 was actually lucky...

Also: (22.30), 17.42, 15.89, 20.96, 21.66, 20.99, 18.75, 21.53, 21.70, 18.87, 17.25, (15.17) > 19.50 avg
(No so sure about the 15; it wasn't a PLL skip.)

My latest LBL average.
Still trying.

Another question. Do you guys rotate alot when slotting in the corners and edges? Cause i do.

chaotarroo: When you post times from an average, it's nice if you post the average with it. ;-)

Anyhow, this is a vid of my "speed LBL." Now Harris or Yu Nakajima needs to make a faster one.

 

[newbiecubie]

My best is (look in my sig) I am starting to meorize PLL. I have done the common simple ones which pop up commonly.

erik made a sub 20 lbl video average

Yes, here it is:
