Stopwatch Practice

Three drills for the skills that take real reps to build: catching stroke cycles with the 3-cycle method, counting strokes across a length, and recording lap splits without stopping the clock.

Watch the circle pulse on each simulated hand entry. Press Lap on entry 1, then again on entry 4 — that's 3 full cycles. I'll calculate your measured stroke rate and compare it to the actual simulated rate.

ENTRY
Press Start, then tap Lap on each pulse.
