Breath Count calculations are explained in this brief help article.
Breath count is gauged by a swimmer’s head movement and maximum head tilt. When the swimmer’s head is tilted on an axis, TritonWear will pick this up and classify this as one breath.
TritonWear makes a judgement call for breath and non-breath movements in each stroke. This judgement call is based on previously recorded data from the same swimmer. This distinction is made because different swimmers have varying degrees of movement when taking their breaths.
For freestyle head tilting to the side = 1 breath
For breaststroke and butterfly: head coming up and back = 1 breath
