It's essentially a basis for getting most of the pieces solved in as few moves as possible. Then, you find ways to solve the last few pieces while retaining the skeleton.

...I think.

2. i didn't want to ask this in the q&a thread because i thought id get a better answer here:

what does "NISS" stand for?

"Normal Inverse Scramble Switch".

4. I just got this in the German forum competition. Possibly the best (and luckiest) edge insertion ever!

Scramble: U L2 D B2 R' D' F2 B U F2 D L2 U' L2 B2 D' B2 R2 D'

2x2x2: F2 R' . U' D B' D B
2x2x3: F2 R' D R
Pseudo F2L-1: R L' F L F' R'
U-Perm: D B D' B' L' D L'

. = L2 U' D F2 U D'

Zusammen: F2 R' L2 U' D F2 B' D B F2 R' D R2 L' F L F' R' D B D' B' L' D L'

25 moves

5. 1. U F2 L2 D F2 L2 U L2 D2 U' R' F D' U' R B2 U' L' F R2 U2

x2 F2 U F2 U' D L D2 // 2x2x2 [7]
F U2 L F2 L F L' F' y2 // 2x2x3 [8/15]
R U' R' U' R2 U2 R2 U F R2 F' // EOF2L [11/26]
y' r' U' R U L U' R' U F' // ZBLL [9/35]

2. D' L2 B2 D' L2 U R2 D2 L2 F2 R' B U F' L2 U' B2 U R' U2

y F2 R' F' R2 B L' // Rouxblock [6]
U D F U2 x2 // 2x2x3 [4/10]
y' R' F R F' R U2 R' U' R // EOF2L [9/19]
y R U2 R' U2 L' U R U' R' L // COLL [10/29]
U // EPLL [1/30]

Is there any way I could've made these better? They were both ridiculously lucky.

6. Saarland Open 2012 scramble: D2 L2 B R2 U2 F' L2 U2 B2 L2 F' D L2 B U L' U2 L' F' R'

Extremely good scramble. Quite many nice starts were found both on normal and inverse.
Actually Tim found 24 moves (18 moves to leave 3 corners) and Sébastien found
25 moves (17 moves to leave 4 corners). Congrats! Maybe their solutions will follow.

Unfortunately I couldn't find any good solution in time. Some of my attempts:
Spoiler:

[1]
2x2x2 block: B D' F' R' and F2 makes c/e pair.

[2]
1st square: R D2 F
2nd square: B'

[3]
1st square: R' F'
2nd square: B'
c/e pair: U R U'
2x2x3 block: F D' F' L2

Then still there're many continuations. For example

Finish F2L: L' U' L U' F' U' F', or
Finish F2L: L' R U' L R' F' U F, or
Finish F2L: L' R U' L U' R' F' U F, or
Finish F2L: L' R U' L U B U B' R' and so on,

but I did not investigate so much after that in reality.

[4]
In most of my time I investigated this one.

Pre-scramble: R'

2x2x1 block: B2 U' B'
2x2x2 block: D'
2x2x3 block: F'

On inverse, I found F2L-1 + EO in two ways. So on normal,

Pre-scramble: L2 U B L2 B' U' R' or
Pre-scramble: L2 U F U2 F' U' R'

and the start B2 U' B' D' F' makes it. I searched continuation several times
after that, but I couldn't find any good finish in time.

The clock was ticking, and I decided to write down a safe solution as follows.

Pseudo 2x2x3 block: B2 U' B' D' F'
Pseudo F2L minus 1 slot: L' F U' F' U2 L (***)
All but 5 corners: R' U B' U B + U2

17 moves, but no time to search good insertions, so just did:

Insert at the beginning: L' F' L B2 L' F L B2
Insert at +: B L' B R2 B' L B R2 B2 (A-perm)

Solution: L' F' L B2 L' F L U' B' D' F' L' F U' F' U2 L R' U B' U B2 L' B R2 B' L B R2 B2 U2 (31 moves)

When I wrote down the solution almost no time was left...
According to Insertion Finder, the optimal insertions are:

B2 U' B' D' F' L' [@1] F U' F' U2 L R' U B' U B U2
Insert at @1: L' F2 L B L' F2 L B'
After the 1st insertion: B2 U' B' D' F' L2 F2 L B L' F2 L F [@2] B' U' F' U2 L R' U B' U B U2
Insert at @2: U' F' U B' U' F U B
Fewest moves: 25. 8 moves cancelled

After 1-hour, Arnaud showed interest in the start above,
and found some nice finish as follows:

Pre-scramble: U2 R'

Start: B2 U' B' D' [U2] F' (U2 inserted)
Finish F2L: L' U' L B' U B
All but 3 corners: U B L B' L' U' L
Correction: U2 R'

21 moves to leave 3 corners.
And another one he found:

Pre-scramble: L' R'

Start: B2 U' B' D' F'
F2L minus 1 slot: L' F U' F' U2 L2 (exactly the same as my start (***))
c/e pair + EO: U' L' U2 L
All but 3 corners: F U2 F' U'
Correction: L' R'

also 21 moves to leave 3 corners. Well done Arnaud!
(Both skeletons give 27-move solutions)

And I'm disappointed at my result again, I'm now getting into a slump both online and official...

7. The scramble really was awesome. Adrian found a 15-moves F2L and I found an 18-moves F2L. We're both not really good at FMC though :P
Scramble: D2 L2 B R2 U2 F' L2 U2 B2 L2 F' D L2 B U L' U2 L' F' R'
z' F' D2 F2 L'
U R U R2
L' U2 L2 U' L' U R
(he used edge control in his final solution anyways)
My solution:
R' B' U R D'
U' F' L U L
U F' U' F
U2 F U F'
(I also used different insertions in the end, anyways, just to show you how awesome this scramble was )

8. is this the scramble of the saarland open fmc?

9. Here's my NAR 24 from Saarland:

Scramble: D2 L2 B R2 U2 F' L2 U2 B2 L2 F' D L2 B U L' U2 L' F' R'
Spoiler:

Solution: D' F D F' R2 F R2 F' R2 B' D' B' U2 B D' B' U2 B' D F2 L2 F U' R (24)
Use the inverse scramble:
2x2x2: R' U F' L2 (4|4)
2x2x3: F2 D' B' * D2 B (5|9)
F2L-1: R2 F R2 F' R2 (5|14)
F2L and LL edges: F D' F' D (4|18)

Insert B' U2 B D B' U2 B D' (6) at * for 2 moves cancellation = 24.

I think we got WR podium: 24 + 25 + 29 (Jan Bentlage) = 78

10. My 25 move solution:

I'm especially happy about it, because it did something within this attempt I had never done before, not even at home. And apparently this helped a lot!

2x2x2 on Inverse: R' U F' L2
Switch and 4 corners: U F' U' F2 D' F2 D . F2 B' D2 B D F'

I wasn't satisfied with the amount of cancelling moves for the insertions I found in there and the Insertion Finder confirms me, that 28 moves is optimal for that skeleton. BUT:

I quickly saw that . = D' F2 D B' D' F2 D B, which cycles my not solved pieces but in a not helping way cancels A LOT of moves, indeed it cancels 8 moves and so I decided to insert this and get a slightly different skeleton:

4 corners: U F' U' F2 B' D' F2 . D F2 D2 B : D F' L2 F U' R

. = F2 R' B' R F2 R' B R
: = B' D F D' B D F' D'

Solution: U F' U' F2 B' D' R' B' R F2 R' B R D F2 D' F D' B D F2 L2 F U' R
