Zone Entries
The device must register a speed between the speed zone thresholds for 5 consecutive samples at 10Hz (0.5 seconds).
*Note – Two entries cannot be registered within 3 seconds of each other.
Example:
The first speed effort displayed on the graph below is an Entry Zone 5 as the speed exceeds 5.5m/s (and remains less than 7m/s) for more than 0.4 seconds (3.3 seconds in this case). The subsequent entry to Zone 4 with a speed between 4m/s and 5.5m/s is not registered as it occurs only 2.6 seconds after the previously registered Zone 5 entry. The minimum time between zone entries is 3 seconds.
The following Zone 4 entry is registered on the Apex device & STATSports Sonra software as a speed of 5.45m/s is achieved with no entries recorded in the previous 3 seconds. The duration of the Zone 4 entry is above the Zone 4 threshold of 4m/s, with an effort duration of 3.2 seconds (above the threshold of 0.5 seconds). The final entry into Zone 4 is no registered as a Zone 4 entry as the previous entry elapsed only 2.5 seconds previously (less than the 3 second window required).
*Note that there are absolute & relative variations available for users.
Distance Zone 1 - 6
The distance covered within the boundaries of each speed zone. This is the exact distance within the zone boundaries calculated from the raw speed data, with no criteria applied for dwell times or exit speed percentages.
