What this metric measures
Training duration is a timeline measurement. Depending on the client and session mode, paused time may be included unless an active-duration field is explicitly available.
How Trampoline Lab calculates it
The client records session start and end timestamps and calculates the non-negative elapsed duration. Imported videos can use media duration as a supporting source.
How to interpret it
Use duration together with jump count, frequency and pauses. Duration alone does not show how continuously or intensely a person moved.
Limits and responsible use
Backgrounding, interrupted recording and clients that do not report pauses can make elapsed duration differ from active movement time.
