Trend sparklines
The idea: re-measure the same firm on a real cadence (quarterly is the natural one) and chart how its AI citation moves. We only have onere-run so far — and it was one day apart, not a quarter — so what’s below is exactly what it looks like with real data, not a mockup, but it is not a trend claim.
Why it moves so much:N = 1 sampling has real run-to-run answer variance — this is the same point the study itself makes about not treating a single pass as a trend line. A real sparkline needs several evenly-spaced re-measurements, not two snapshots hours apart.

If a standing, quarterly-refreshed index is worth building, this is what its charts would look like — with several more points, evenly spaced, per tracked firm.
