Short Race and Category Enforcement

Quick question. If I do a short race (under 20 minutes) at a higher wkg than what my 20 minute power is, will it change my category or will it just show possible improvement in my 5 minute power?

Is it only races over 20 minutes that determine your category placement?

Category Enforcement’s calculation looks at power output at a variety of durations and it understands that doing higher W/kg for a shorter time is not the same as doing the same power for a longer time. All rides you do in the game can affect your category, not just races, and there’s no specific duration that is used to determine your category. That used to be the case but not any more.
