TOTAL IMMERSION
Let’s begin by asking: “why count strokes?” The most important reason is that Stroke Length (SL) is the efficiency measure which correlates most strongly with superior performance in all strokes, all distances and all ages or ability levels. Counting strokes is the only way to monitor SL as you swim. Knowing your stroke count on any timed swim or repeat gives you a more complete understanding of the quality of that swim than if you only knew your time.
