Same here, Im very data driven. Everything lives in one dedicated spreadsheet, and youd probably guess I have OCD. It has daily logs of supplements, enhancers and peptides, resting heart rate, blood pressure, body fat scale readings, daily calories, and weekly tape measurements on every muscle group. More sheets smooth the daily calorie and scale numbers across a moving five-day window and show weekly momentum averages, so I can compare average weekly intake against average weekly weight, fat and muscle change. Honestly this data let me recomp with little effort: I reached 10-11% body fat and put on 15lbs of muscle after that.
