Not good... The 4x4 is terrible usually I average 4:30, which is also terrible. BLD was really close, but that's ok because I've only been able to solve BLD since yesterday.

Actually did pretty good compared to what I usually get lol.
 
3x3 (22.98) 19.48 16.84 (16.07) 18.81 Average 18.37
Pretty bad, its late and I'm not that warm.

2x2 5.68 6.36 5.94 (8.20) (4.87) Average 5.99
Woah, this is very good for me.

2x2 BLD 31.34 31.39
I made mistakes on both of these.

3x3 BLD 1:41.55

I'm very interested in Per's skeleton then 2 corner cycle insertions technique now that I understand FMC a little better than the first time Per showed me this approach. I tried it on this week's scramble and found an improvement to my solution (obviously this is just practice, and does not count as my competition solve).

U2 L' D' L U2 L' D L' U B' F2 D2 L' U F' R' F2 R U R' U R2 U2 R U R' U' B U' F2 U B' U' (33 HTM)

Here is how I constructed it. First do premove F2, then the skeleton is:

2x2x2: . L2 U B' F2 D2 L'
pseudo-2x2x3: U F' R' F2
solve the remaining edges: R U R' U R2 U2 R U R' : U2

This leaves 2 double swaps in the corners where each double swap has unbalanced orientation of the two pieces. These cases I solve using 2 three cycles and therefore insert [U2 L' D' L U2 L' D L] at the dot and {U' B U' F2 U B' U' F2 U2} at the colon. The best part is that the insertion at the end cancels the last turn of the skeleton and the application of the premove when the scramble is done correctly, cancelling 4 moves!

Ok so this scramble is still sup-30, but still it is my very first ever attempt at edges first, and I think I didn't do so badly for a first attempt ;-) I will definitely have to try this again, this was fun. May I ask, Per, how you approach solving the last edges after building the 2x2x3, and how on earth do you optimize the two corner insertions in under an hour?? I am humbled after now having actually tried this technique.

Hello Chris, well done, I seldom use this technique and it cost me a lot of time. I only once did a double-corner insertion within the hour and I doubt if Per ever used it within a one hour solution, unless he uses his Cube Companion software which is allowed for FMC at Dan's site but not for this or official competition.

2x2x2: 9.78 9.68 8.43 10.47 8.34 = 9.30
3x3x3: 23.09 29.11 27.50 27.06 25.88 = 26.81
3x3x3_oh: 42.84 51.11 40.09 56.34 34.58 = 44.68
4x4x4: 1:52.41(O) 1:39.06(P) 1:34.25 1:38.52 1:29.05(P) = 1:37.28
5x5x5: 2:52.31 2:57.94 2:55.97 2:54.55 2:27.83 = 2:54.28
2x2x2_bf: 1:32.25, 1:29.47 = 1:29.47
3x3x3_bf: DNF, DNF = DNF
Relay: 5:10.47(P)
Square-1: 1:12.40 1:53.91(P) 1:44.40 1:38.66 1:27.03 = 1:36.70

PyraMinx: 21.56 12.43 13.38 11.21 22.75 = 15.79
Fewest Moves: 30
Solution: L' B L B U B' U' B' U' B2 U2 L2 B U' L R D' F' R U' D B2 R2 F2 U' F2 L2 F2 R2 L2
Explanation: Inverse scramble U' R F2 D' B U2 B' L2 D B2 R U2 D B U' R' F D'
2X2X2 (6): D2 U R' F D R'
2X2X3 (10): L' U B' L2
Rest of first layer + 1 middle layer edge (13): U2 B2 U
final middle layer edge + corners last layer (21): B U B U' B' L' B' L
This leaves 6 edges that need permuting and 2 edges that need orienting after 21 moves. If you think it is impossible to do that in only 9 moves, look at these insertions:
Permute 4 edges (6): L2 R2 F2 L2 R2 B2 before the 2x2x2 block
3-cycle of remaining edges (8): B2 R2 F2 U F2 R2 B2 D after the 4 permuted edges and before the 2x2x2 block cancelling 5 moves
L2 R2 F2 L2 R2 B2, B2 R2 F2 U F2 R2 B2 D, D2 U R' F D R', L' U B' L2, U2 B2 U, B U B U' B' L' B' L

Those are very nice insertions Chris. I cannot imagine finding these within an hour (I suck at corner insertions, but I can do edge-insertions very fast)

Guus, we seem to be tied again. I am just glad we found a completely different solution this time :)

Hey Arnaud, I was just wondering if you are still planning on posting the rest of the results up to the current competition by the end of the year. I know you're really busy, so this probably is not possible, but if you need help, I could try doing some of the results.

2x2x2 BLD
DNF, DNF
Still working on this

3x3x3 BLD
DNF(4:44.54), DNF
The first was only off by two rotated edges, the second was dismal. I've been working on this, but no payoff.

I know I have been saying this a lot of times, but I actually have a lot of these results already in my database. I just have to sit down and start posting them (nicely formatted and all). All results should be there by the end of the year.

4x4x4
Average: 2:26.63
Times: (2:22.84), (2:33.23), 2:27.96, 2:23.70, 2:28.23
I really seem to be stuck at this 2:20.00 mark, I'd say about 60% of my solves are under 2:30, more towards 90% are under 2:40. But not one sub 2:20 solve yet.
 
Jefferson James

2x2x2
Average= 7.59
7.83, 6.86, (6.31), 8.09, (8.55)
Just practicing 3x3x3 makes these times a little better for me.

3x3x3
Average= 21.82
22.89, 20.02, (18.95), (23.22), 22.56
I practice over 6 hours a day now that im on break.
