Keith, keep in mind that data accuracy comes in many
forms. Russ talked about data variability. This is a
big one because if data which you record is not
stable, it is also not reliable, even as a comparison
to other data from different runs. Being off a few
degrees may or may not be a problem for you but if the
data is variable, you have garbage and it will not
correlate to other data.
