Somehow, 2-generator isn't done enough. So, here's a contest of 12 scrambles to compare our 2-gen times (and so that I can see if my 6.xx avg is in danger :p). Scramble 2-gen, solve 2-gen, record your times:

1. R2 U R2 U2 R U' R U' R' U' R' U2 R' U' R U'
2. R' U R' U2 R2 U2 R' U' R2 U R2 U2 R' U2 R U'
3. R' U2 R' U2 R U R U2 R U2 R' U' R U2 R' U'
4. U R U R2 U' R U' R U R2 U R U' R U' R
5. R' U' R2 U R' U2 R U R' U R2 U R U2 R2 U2
6. R' U R U' R U2 R' U R2 U' R2 U2 R U R2 U2
7. R' U R2 U2 R U2 R2 U2 R U' R2 U' R2 U' R U2
8. R U' R U2 R U R2 U2 R U R U' R2 U2 R2 U'
9. U2 R2 U2 R' U' R2 U2 R' U2 R U2 R U' R2 U2 R'
10. R2 U' R2 U2 R' U2 R U R' U' R' U' R2 U2 R' U2
11. R U' R' U2 R2 U2 R U R U2 R2 U R' U' R U
12. R' U2 R2 U R' U2 R U' R' U' R' U R2 U R' U'

(9.19), 7.48, 7.06, 6.72, 8.45, 8.18, 7.41, 9.01, 5.71, 7.77, 9.18, (5.13)
>7.70, bad :p

By the way, I can't prevent side-talk, but could we keep it to discussing times , algs, etc. instead of "wut's 2gin? is it just twisting 2 sides?" (it is) and "can i allowed to twist F face in my solve?" (No, you may not. But you're welcome to create a new event for that.)? ;)

Times: 10.42, (14.93), 14.42, 9.09, 13.83, 12.55, 8.91, (6.67), 10.73, 8.94, 10.97, 8.21

Avg: 10.81

I was going for sub-10 here but I failed! Not knowing a 2-gen Z-perm doesn't help.

Very bad, no warm up.
The 22 was a pop.
Average: 14.48 seconds
Individual Times: 17.41, (22.41), 12.72, 17.20, 19.42, 14.34, 11.12, 14.52, 17.25, (08.98), 09.89, 10.88

I hate the 2-3 look OLL and Z perm. They are the sup-14s. If I know the 2gen OLL and PLLs, I can average sub-10. The last 3 are the usual 2LLL. I remember doing this a few weeks ago and getting a few sub-7 solves and a 10-12 second average.

Average=8.40

Alright my goal was to lose by less than a second to Lucas. Those first three solves were 2gen warm ups.

=6.21 seconds.

Lol I remember trying this back when I was around 20s, and I got 7s just because of PLL skipped (averaged around 10-12 with 2 gen at the time). I was using 2 step OLL for some of the OLLs (based on Joel's beginner tutorial)

9.97 average...
I think I can do faster OH as RU turns are much more natural there.
This makes me want to finish the 2GLL algs I generated...
Where can I get random 2gen scrambles? I can't join the chat for some reason to get them there.

Along with the Chat Room link from this forum, there is this, which connects to the same place: http://www.strangepuzzle.com/chat.php . I doubt that is the difference, but it is worth a try.

My times:
Average: 08.56 seconds
Individual Times: (06.05), (10.45), 09.34, 06.97, 08.55, 08.81, 08.34, 08.86, 08.61, 09.03, 09.02, 08.03

you can always use regular scrambles and ignore the letter, only paying attention to the ', 2, or plain letter demarcation and just alternate R and U.
so D' L2 F R U2 B' would become R' U2 R U R2 U'. a little slower to scramble but i think it would work.

also lucas i'm sorry for side-talking but i think this falls under the "etc" that you mentioned. i will do these soon.

4.31 5.36 6.38 4.36 6.11 (8.38) 7.59 6.40 (4.09) 6.47 5.65 4.96 => 5.76

Suck on that Lucas! (tons of easy scrambles)

I've been wanting to run a competition like this ever since I noticed the category had disappeared from speedcubing.com. I'd like to see it back, and I think high quality scrambling and many interested people could achieve it.

Okay, just so you can all laugh at me, here I am. I've never tried it before; I did a few solves first to make sure I could do it at all. I use hardly any 2-gen algorithms, so I have very little to work with - all I have is Sune, a U perm I don't know very well and am therefore very slow with, and the rest is intuitive.

31.71 seconds:
28.16, 16.97, 41.98, 23.89, 25.80, (1:21.34), 29.26, 27.31, 1:03.50, 21.28, 38.98, (12.75)

On the worst one there, I put a pair in the wrong way into the wrong slot, and spent about 30 seconds trying to get the other pair to go in the other wrong slot until I realized what I did wrong.

Wow, I'm about the same at this as I am with regular 3x3x3. How sad. :)

At least I had a good last solve. Maybe I was just starting to get better when I quit.

Mine would be: DNF (unless I didn't have to cycle corners in a single solve). I can't 2-gen corner cycle.
Stefan is right. If you scramble with 2 sides, you can always solve with 2 sides. And when you only move 2 sides, the corner permutation is always correct. Just solve F2L and orient with sune and finish with U perm (unless you know more optimal algs).
