Notes from people who had to say a weight out loud

The Signal Weighting Lab did not make our DAU chart prettier. It made the chart smaller. We stopped counting lock-screen peeks. Leadership asked why the score fell in week five; we had the change log from module two. I would have liked more help choosing a visualisation library. Helen declined, on principle. Fair, if slightly stubborn.

Useful if your event names are already adult. If they are still “btn_click_2”, budget two extra weeks of inventory before you enjoy anything.

Review on a UK learning board · “source-stackhub-lab”

Quiet-week rules from Sparse-Event Scoring stopped us emailing dormant admins who were simply waiting for quarter close.

Client in public-sector digital: we needed a score that a non-technical director could distrust productively. The board sentence module was the piece we reused. The live argument was bruising. We still booked Critique Hours after.

When “engaged” meant “opened the badge”

A Manchester workplace product scored anyone who expanded a notification cluster. After the lab, that event kept a weight of one; completing a shared task kept twelve; reopening the same task because the assignee list was wrong was scored as product debt, not loyalty.

The team’s headline number fell for six weeks. Support tickets about “missing colleagues” fell with it. They still argue about the twelve. That argument is now in writing, which is the point.

Silence was not a cliff

A Cardiff analytics vendor treated fourteen quiet days as a churn watch. Sparse-Event Scoring rebuilt the expected cadence from invoice cycles. The score now has a “calendar-aware” band. Sales still wanted a red light. They received a paragraph instead.

Limitation they named themselves: the model is useless for brand-new tenants with no invoice history. The studio did not pretend otherwise.
