It breaks the footage into splits, pace, stroke rate, distance per stroke, 15m times, underwater time, turn times, and more.
3

OmniCoach coaches it

The numbers become plain feedback, a race plan, and notes you can act on.

What StrokeLab measures

Length splits

Every length on its own, so you can pinpoint where time was won or lost.

Pacing

Pace per 100 across the race: opened too hard, or built when it counted?

Stroke rate

Real tempo, not a guess. Know if speed came from turnover or length.

Strokes per length

A climbing count flags fatigue, short strokes, or weak breakouts.

Distance per stroke

How far each stroke travels, linking technique and power to the clock.

15m times

Your time to the 15m mark off the start and turns, where underwaters win or lose races.

Underwater + breakout

Total underwater and breakout time on each length, so you can see what your dolphin kick is buying.

Turn time

Time in and out of each wall, so you can see whether turns are quick or costing you.

OmniCoach Example feedback

“Your tempo held through the first 100, then dropped about 8% after the third turn while your stroke count crept up. Back-half pacing stayed strong, so the time to find is in your breakouts. This week: 8×50 holding stroke count off fast walls.”
