NISS Notation

Quoting myself from this post on speedsolving.com:

I’d like to introduce my notation for NISS solves, because I find it easy and practical. If you like it, we can use it (or something similar) as standard notation
The rule of thumb is: a ‘(‘ means “switch to inverse scramble using the inverse sequence of the moves found for normal scramble as premoves”, a ‘)’ means “switch to normal scramble (…)”. An example will make it easy for everyone to understand:

Scramble: R2 F D2 F’ R2 B’ D2 B’ F’ L2 F U’ F2 L’ U2 B R’ F D2 F D’
Solution: L2 D’ L2 R B L F’ L’ F R’ U2 F’ U F U2 F U F’ U’ R’ F’ L F L’ F’ R2 F2 R2 (28 HTM)

Solution (written without this notation and with comments):
On normal scramble:
L2 D’ L2 //2x2x1
On inverse scramble with premoves L2 D L2:
R2 F2 //Another 2x2x1
On normal scramble with premoves F2 R2:
L2 D’ L2 //Two 2x2x1
R B R’ //Pseudo 2x2x3
On inverse scramble with premoves R B’ R’ L2 D L2:
R2 F2 R2 F R //XX-cross + pair in slot
On normal scramble with premoves R’ F’ R2 F2 R2:
L2 D’ L2 R B //XX-cross -1 move + pair ready (5/5)
L F’ L’ F R’ //F2L -1 + pair ready (5/10)
U2 F’ U F //F2L (4/14)
U2 F U F’ U’ R’ F’ L F L’ R //LL (11/25)
R’ F’ R2 F2 R2 //Undo premoves, 2 moves cancel out (3/28)

With my notation:
L2 D’ L2 //2x2x1 (3/3)
(R2 F2) //Another 2x2x1 (2/5)
R B R’ //Pseudo 2x2x3 (3/8)
(R2 F R) //XX-cross + pair in slot (3/11)
R L F’ L’ F R’ //F2L -1 + pair ready, 1 move cancels out (4/15)
U2 F’ U F //F2L (4/19)
U2 F U F’ U’ R’ F’ L F L’ R //LL, 2 moves cancel out with premoves (9/28)
