Don't worry, Rust Bucket, I caught the
ad hominem attack the first time. I didn't remark on it because it wasn't remarkable. But it did entertain me.
(That is what you mean by your user name, isn't it? A coupe is an old car, and a car the color of an old tomato is going to be rusty, so your user name implies an old, rusty car -- what we often call a "rust bucket.")
Anyway, back on topic:

After I get through calibrating the wheel sensor, I do know the magnitude and sign of the error.
When I calibrate something, I compare the measurement of the device (the wheel sensor plus whatever's counting wheel revolutions) to a known standard (like a surveyed distance). If I ride a surveyed distance of 5 miles, and my device reads 4.97 miles, its accuracy is -0.6%. 0.6% => magnitude, negative => it measures less than the standard.
Now perhaps I don't understand what you mean by "measurement error." But I really don't want to get into an "Alice in Wonderland" kind of situation where I have to worry about what Humpty Dumpty meant every time I read someone else's words.
