What would a metronome marking of 200 be labeled as?

A metronome marking of 200 is typically labeled as "Presto." This term indicates a very fast tempo, generally ranging from 168 to 177 beats per minute, but at 200 BPM, it pushes the upper limits of this category. In some contexts, it may also be referred to as "Prestissimo," which denotes an even faster tempo.
