How it works, and where to write.

Because a pause would let a break hide inside the measurement. The block is a claim about unbroken attention, and a paused block is not that. If you stop and come back, the second sitting is a new block.

Anything under a minute is discarded as a misclick rather than recorded as a one-minute focus block.

Done means you finished what you sat down to do. Distracted means the pull came from you. Interrupted means it came from outside. Ran out of steam means attention faded rather than broke. The split between them is the useful part.

Against attention, not output. Five is losing track of time; one is barely holding it together. A short block you were locked into is a five. A long one you kept dragging yourself back to is not.
