Ok, so if I'm synthesizing your words correctly, other apps are "Bring your program, any program" and you're really leaning on "We'll tell you exactly what to do based on Pareto frontier modeling" ?
My marketing is for a different niche - people who lift weights, see that they have variability set to set and day to day, and want a program that will help them quantify that variability and understand what it means. One thing that works really well in my program is detecting when you need a rest or deload, because the baseline comparison is rigorous and sensitive - if you have one bogey set, it might not mean much, but when you see that even your opening sets are at or below baseline after a stretch of workouts, that's a pretty good signal, and that's hard to get with most apps.
