Category:Turn metrics

A metric (more specifically, move count metric or turn metric) is a convention for counting moves. The same sequence of moves can have different move counts depending on the metric used.

Summary of different metrics

For more details, see the respective articles.

Uses

HTM has been used to. For example, God's number is known to be 20 in HTM. From a mathematical standpoint, however, QTM seems a more natural choice; half-turns are visibly redundant as generators.

Debate over metric in FMC

WCA uses HTM in FMC. There has been a number of debates arguing for different metrics.
