Average Split
What is Average Split?
Average split is the single most important summary metric for any erg piece. It is calculated as: Average Split = (Total Time / Total Distance) × 500. For example, a 2000m row completed in 7:00 has an average split of (420 / 2000) × 500 = 1:45.0/500m. Average split determines your ranking and allows comparison across sessions. During a workout, the PM5 shows both current (instantaneous) split and average split. For testing purposes, average split is the definitive measure. For training, current split helps with pacing but average split is what matters at the end. Because of the cubic relationship between split time and watts, even small improvements in average split represent significant increases in power output.
How Watta Uses Average Split
Watta extracts average split from erg screen photos and uses it as the primary metric for the Work Output component of the Effort Score. Tracking average split at the same heart rate over time is one of the clearest indicators of improving fitness.
