Keeping the dashboard to a short set of tiles that answer what got worse after a release is a good filter. One practical addition is a per template view, since a slow product page and a slow blog post need different fixes and averaging them hides both. Do your agency users ask for a client facing version of that view?

The 'short enough to trust' constraint is the real design rule: a default board with forty tiles trains people to ignore all forty. Deploy deltas sitting next to the vitals is what turns a chart from decoration into a cause.
