Field notes
The walkthrough follows a made-up week, including a logged late coffee, drinks with friends, and changing HRV and sleep. For habit testing, the page proposes randomizing 14 evenings with a habit and 14 without, then reporting whether an effect is likely or not shown. The bloodwork section explains its reference-change calculation and excludes comparisons across different labs.
