Snyder Metric
From Speedsolving.com Wiki
This is by far the simplest method for counting turns.
Every parallel simultaneous move of the puzzle is counted as one turn, regardless of the puzzle shape or the complexity of the turn.
Snyder Notation may be used to represent algorithms that include anti-slices and imbalanced anti-slices, as well as compound multilayer slices and anti-slices.
Examples:
Solving for the U-Twist (headlights) using the Snyder Metric:
R+o' U2 R' U' R U' R'o+ U2 L U L' U = 12 turns
Solving for the H-PLL using the Snyder Metric:
R+o' U2 R'o+ F'o+ U2 F+o' = 6 turns
