Reduce the number of levels/colors associated with the intensity of a set/rep to 3 or 4 max. I can never remember how fast I’m supposed to be swimming when it says moderate vs. endurance vs. best average or threshold vs. race pace vs. sprint. Too many levels! I can’t look it up mid-workout, and I can’t ever remember. Ideally blue = easy, yellow = moderate, and red = all out race pace. You could probably throw an orange in too to mean fast but not all out.

“Best average” is not an intensity level, it is an instruction on how to swim the set. The intensity level is “fast.” The instruction (which should scroll so I can read the entire thing on my watch) should explain “swim as fast as possible while maintaining a consistent pace across all reps.”
