Reply to "Temperature compensation check"

The difference between my two measurements at two different temperatures was 9mm AFTER the temperature compensation. Before the temperature compensation it was 47mm for 100m, or 141mm (5.5 inches) for a 300m cal course. So it is not insignificant.

But I would agree that with the current temperature compensation instructions it is very easy to make a mistake and end up subtracting distance from a course when you should be adding distance. So it might be better to eliminate the temperature compensation from the procedure.

A third option though, would be to just simplify the instructions:

If the temperature is above 68F, leave the course as measured.
If below 68F, add
(68-temp) x 0.00000645 x (course length)
to the course.
