Move latency

One move at a time, timed on the PC's USB bus from the command to the report carrying it. A default move goes through each box's default smoothing, and an immediate move skips it.

Default move latency, p50

Delay in a stream of moves

A steady 2 s stream of one-count moves into a still mouse, each box on its default smoothing. Each count is matched to its command and timed from it.

Smoothing settings

Each box's smoothing settings, measured the same way on the PC's USB bus: 40 single moves into a still mouse, and 100 one-count moves 150-250 ms apart into a moving 1 kHz mouse.

Extra reports

Reports each box emitted while injecting: beside a 1 kHz mouse moving in every report, in a steady stream of moves into a still mouse, and beside a mouse reporting at 1 kHz or 125 Hz. A 1 kHz mouse sends ~2,500 reports in 2.5 s, a 125 Hz one ~312.
