Why this cadence exists at all
Because some things go wrong slowly. An address quietly leaves the published set. A balance you meant to move sits for four months. A note you wrote stops matching what you actually do. None of that announces itself, and none of it is caught by a per session habit, because per session you are only looking at the thing in front of you.
Monthly is roughly right. Weekly is more than the risk deserves, and quarterly is long enough for a retired address to have found a new owner.
