Very nice; I like the simplicity of Running Level (with less options than Strength Level). Where do you get the reference level data from (for running)?
Thank you for the encouragement! Did you find any areas to improve?
The seed standards reference data is mainly from publicly available race data in CSV form and common running formulas used in the industry (e.g. Effective VO2 Max / VDOT). There are plenty of online calculators and literature (mostly based on Jack Daniels' Formula). However this is just a baseline and it'll be based on its own data set in the future (e.g. survey input).
