sigh…
This morning I did a quick check of Gretchen’s calibration and (argh) it looks like when I replaced the battery, it messed things up so I’m gonna have to go back to the track and recalibrate her.
That REALLY blows cause I had her perfectly calibrated prior to changing the battery.
Knock on wood, at least this time I’ll know what I’m doing so it should only take one 400 meter lap to do the calibration and one lap to verify its accuracy.
