The only quantitative measure I have is some handheld stopwatch
timings.  I did 2-3 runs across the same road segment, then averaged the
times.  The variation between runs was not too great, about +/- 0.1sec,
which I took as a modest validation of my technique.  My speedo is not
calibrated, so differences between configurations are more notable than
the absolute numbers.

speed in mph, times in seconds

..and at a later date, on a different road segment (and different
atmospheric conditions), after I got the Lehmann ECU:
