Every RaceBox session behind the measured lines on the chart, exactly as recorded at 25 Hz — so the interpretation can be checked against what the bike actually did.
Speed is the recorded trace, untouched. Engine RPM is that speed multiplied by the gearing, which
is only meaningful once the clutch is fully home — while it slips, the engine is turning faster than this
line says. Acceleration is differentiated from speed with light smoothing and is shown for reading shifts
and roll-offs; no published number is derived from it.
On the 65 SX the shaded bands are the windows fed to the power-curve fit, and the dashed line is the speed that
the fitted curve predicts for those windows. Where dashed and solid sit on top of each other, the power
curve explains the pull. Where they separate, it does not — that is the honest check on the whole method,
and the number is in the table under each chart.
