Slow-Experience Rate

Every visit whose Page structure ready time crosses the three-second threshold is counted toward this rate; the final number is the ratio of those visits to all visits in the range, not an average or a percentile.

This metric sits directly on the line between profit margin and customer loyalty; put simply, it shows what share of your audience ran into a slow, frustrating experience. Averages and percentiles usually hide the painful drop-offs and make the report handed to management look prettier than reality, but the slow-experience rate lays bare the truth of what unlucky users actually went through. When this rate climbs, it means part of your user-acquisition capital is burning away, bounce rate spikes, and brand credibility erodes in the audience's mind. Watching this metric warns product and business leaders that front-end slowness is eating into revenue — and that a fix is needed before frustrated users leave the page for good.
