FATEwiki - Dynamic Test

A Dynamic Test is a simple competition between two (or more) people, with the respective throws determining the (the lowest result), thus basis for the winner's Margin Of Success. (FUG 12)

Joe (Running:Good) tries to get to the destruct button before the Mook (Running:Average). Joe rolls -1 (Fair), as does the Mook (Mediocre). Mediocre (the lower level) becomes the challenge, and Joe not only succeeds, he succeeds with an MoS of 2 (Mediocre -> Fair), which says something about the result.

MoS	Degree	Magnitude	Duration
0	Minimal	Negligible	Instant
1	Competent	Minor	Momentary
2-4	Solid	Moderate	Scene
5-6	Significant	Major	Session
7+	Perfection	Overwhelming	Long term

This table is a lot like the Static Test one, only with the ranges expanded. That's because two folks are rolling, and the potential range with a -4 vs +4 result (a span of 8), is much wider.
