IN PLAIN ENGLISH
A decision log, shown on the dashboard as Notes & ideas, where you write down why you made a decision while you still remember.
WHY IT HELPS
Makes your reasoning explicit at the time, so you can later judge the decision separately from how it turned out.
HOW IT'S CALCULATED
Nothing is calculated. Each note is a dated title and text. Picking something you did from the activity feed — a buy, a sale, a new target — starts a note with that event filled in and the cursor after "Why:". Expected prices, yields or horizons aren't separate fields; write them into the note.
