**Background:**

Squall was developed for the January 2021 Method Development Competition.

The motivation behind Squall's steps are that a method’s speed depends on two factors:

(Solve time) = (movecount) ÷ (TPS)

The TPS can also be broken down into two factors:

TPS = (max TPS) × (proportion of solve spent turning)

These two formulas can be combined:

(Solve time) = (movecount) ÷ ((max TPS) × (proportion of solve spent turning))

This shows that the factors that contribute to a method’s speed are movecount (efficiency), max TPS (ergonomics), and the proportion of the solve spent turning (lookahead). With that in mind, Squall was made with the goal of good ergonomics, good lookahead, and good movecount.

**Steps:**

1. EOSquare: Solve a square in dbL while orienting all the edges. (8 moves)

2. L pair: Solve the dFL pair, extending the square into an EOFB. You have a lot more freedom here than in CFOP, since the entire right side of the cube is free. (5 moves)

3. DFDB: Solve dM (the DF and DB edges, along with the M centers), extending the EOFB into an EO2x2x3. (5 moves)

4. B pair: Solve the dBR pair. You have a lot more freedom than in CFOP, since the R layer is free. (5 moves)

5. F pair: Solve the dFR pair. You have slightly more freedom than in CFOP, since you can disturb the DR edge, although there are more cases where an dFR pair piece is stuck in the DR position. (7.5 moves)

6. CDRLL: Solve the remaining 4 corners as in COLL, but the DR edge can be disturbed, leading to better algs. (42 algs, 11.5 moves)

7. L5EP: Solve the remaining 5 edges. These algs are almost all RU or MU. (16 algs, 11 moves)
