Each column is the max interval within a slice of the latest reports. A flat teal band = steady polling; spikes = dropped or coalesced reports.

Interval Distribution

—

Histogram of all report intervals this session. Browser timestamp quantization may affect sub-millisecond bins.

Velocity Profile

—

Instantaneous speed in px/s across the latest reports, max-pooled into columns. Y-axis auto-scales to the 98th percentile.
