Could someone explain how to NISS solutions?
like mainly which premoves you're supposed to do to find continuations if you're switching between scrambles a lot?
Let's say I have a 2x2x3 pseudo block (pre-move R') and I want to switch to the inverse scramble what do I have to do?
Pre-move>inv. 2x2x3> inv. Scramble or
inv. 2x2x3>pre-move>inv.scramble?
And why?

Today I did my first FMC attempt, I did go to FMC USA 2014, but I really don't count that because I didn't know anything about FMC. Here was my solve.
Scramble-D' L2 D2 L2 U R2 D L2 F2 D L2 B' L2 D' L2 U2 L D2 L D' U
2x2x1// D' L2 (2/2)
2x2x2// B' U' L U (4/6)
Fixed 2x2x3// R2 D' L R2 B' R2 B2 U2 L U2 L' (11/17)
F2L-1// R2 F D B2 D' F' (6/23)
F2L// B2 R B2 R' B' U' B2 U B' R B R' (12/35)
OLL// B' U R B R' B' U' (7/42)
AUF// B2 (1/43)
Final Solution: D' L2 B' U' L U R2 D' L R2 B' R2 B2 U2 L U2 L' R2 F D B2 D' F' B2 R B2 R' B' U' B2 U B' R B R' B' U R B R' B' U' B2 (43*)
I know the 2x2x3 was terrible but it was the best I could find(in like 3 minutes). Once I saw the 8 move LL I didn't care about the 2x2x3. I also know that I should have put the AUF at the start of the OLL and cancelled a move.
Bold: I wrote down a wrong solution to F2L, and once I realized that, I CFOP solved it and got the 8 move LL. I did the solution I would have done if I didn't do that, and I got 63
Other than the block building is there any other major things I need to improve on? I do know a bit about insertions and how to do them, but what else do I need to know?

i'm no professional, but you can easily do your 3x2x2 in less moves than 23, especially on this scramble.
here is an EO 3x2x2 that leaves you with an easy F2L pair:
U D R F' D' F'
D' R U' D B' U B'
it is not always good to solve the EO during the 3x2x2, but it's a familiar state for ZZ/Petrus solvers, which makes it easier (at least for me) to see lucky cases

Thanks, I see what you mean, but I'm not an expert at Petrus or ZZ, so I probably wouldn't do that. I'll look into that though. Did you mean 2x2x3 in 17 moves?
Actually, I had written down: R2 F' U' F2 L' U R' L2 F R2 D2 L F2 R' F2 L U2 D2. (prime after the R on the seventh move)
My solution - 26 moves:
2x2x3: L F' R F' R2 F2 premove F2
Rest of F2L: U F' . U2 F2 R' F' R
pseudo OLL leaves 3 corners: R B L' B L B2 R'
insert at .: F R F' L F R' F' L'
14 move F2L! Then a really lucky psuedo OLL to 3 corners. Insertions didn't help much, though.
to those at dinner: I guess I didn't really remember it right - I was confusing this with one of the other solves today, I think. I was right about the F2 premove, though.
I finally left the 31 club today, after being a member for over 4 years. And I did it in style, with a 31, a 30, and a 26. 29 mean. All of the solves felt as lucky as this one (even if the other scrambles didn't look quite as lucky).

Nice solve, and nice mean!
Oh, and welcome to club 26
Here is my quick attempt:

L' U' L U F //square
Switch to inverse

The winner Shuto Ueno got 30, 29, 27 = 28.67, which set a new Asian record. Congrats!

Here is the 25 single I got at Another FMC 2015 (best single of the comp) on my first ever official attempt:
Scramble: D R2 D B2 D' B2 U F2 D B' R' D L2 B' L U R U L B2
R2 D' F U L U2 L' // lol 2x2x2
B D2 // 2x2x3
R' B R' B2 D B D' // F2L - 1
B2 R B' R' // F2L
R D B D' B' R' // OLL
B' // PLL skip + AUF
final solution: R2 D' F U L U2 L' B D2 R' B R' B2 D B D' B2 R B' D B D' B' R' B' (25)
no insertions or NISS lol
I found this because I tried doing 2x2x2 on different blocks, and this one was bad but led to a 9 move 2x2x3. I then solved the cube so I could try switching to inverse, and after I solved the first F2L pair, the second one was paired in the top layer. After inserting the second F2L pair, I had a 7 move LL and went back and wrote down that solution.
Also, I had an 8 move F2L - 1 on the stupid 3rd scramble:
Scramble: R2 F' U' F2 L' U R' L2 F R2 D2 L F2 R' F2 L U2 D2
on normal: L // lol 2x2x2
on inverse: F U' F' R2 F // add a 1x2x3
on normal: F' R // F2L - 1
U L R' U F' R2 U' R2 U R2 U2 R2 F [@1] R F' U R U'
Insert at @1: F' R' F2 B2 L F L' F2 B2 R
Fewest moves: 24. 4 moves cancelled
The final solution: U L R' U F' R2 U' R2 U R2 U2 R F2 B2 L F L' F2 B2 R2 F' U R U'
