The tracking rule follows directly from feedback speed.
Daily: the process. Did you do the thing. Binary, no interpretation, ten seconds.
Weekly or monthly: the outcome. Where is the number, and is it moving at a rate that reaches the target by the date.
Monitoring progress is not a nice-to-have here. A 2016 meta-analysis in Psychological Bulletin covering 138 studies and 19,951 participants found that interventions promoting monitoring of goal progress reliably improved goal attainment, with a larger effect when the information was physically recorded. Recording matters more than remembering. But you can only record something daily if it is a behaviour, which is the practical argument for the process being your daily metric.
The outcome review is where you get to change your mind. If eight weeks of a well-executed process has moved the outcome less than the pace you need, the honest conclusion is that the process is wrong, not that you need to try harder at it. Most people do the opposite: they keep the method and blame the effort.
