Description :
This report calculates the percentage of time an animal moved at an average speed within different intervals.

Calculation method :
The calculation takes place in 2 steps:
Step 1: EthoTrack calculates the average speed of the animal over each averaging period.
Step 2: EthoTrack groups the periods during which the average speed belongs to the same speed interval and calculates the percentage of the total time.
Example :
Analysis time: 10 minutes.
Averaging time: 1 minute. Equal intervals: width = 5 mm/s.
Step 1: EthoTrack calculates the average speed of the animal over each period: 0 to 1 min, 1 to 2 min, 2 to 3 min, ...., 9 to 10 min.
For example :
|

Step 2: EthoTrack groups the periods during which the average speed belongs to the same speed interval and calculates the percentage of the total time.
