Working notes on training, energy and measurement.

Principles

• The 179-Calorie Problem The number is smaller than the error bar on any method used to estimate it, which is the whole reason to stop estimating.
• What the Scale Is Actually Telling You The signal is smaller than every source of noise on the list. That asymmetry is the whole problem and the whole solution.
• Why Base Has No Single Fitness Score The most requested feature that will never ship, and the reasoning behind refusing it.
• Why Every Number in Base Shows Its Own Math Every derived number opens a plain-English explanation of the formula that produced it, in the same words as the code comment next to it.
• Why We Built Base: The Spreadsheet That Kept Breaking The problem was never any one app. It was that the interactions between them were where all the information lived, and nothing owned the interactions.
