Second that - I read the whole thing a few weeks ago. I

Hi all,
While this list is essentially a list for EMC controller discussion
an occasional passing word on precision and accuracy might be
appropriate.
Definitions:
accuracy : the ability to hit the blueprint values
precision: your repeatability
You can adjust your code to hit the spec dead

Gentlemen,
Sorry for this in advance. I couldn't resist.
Stephan Wille Padnos: you are too kind
Steve Thornton: I rest my case
thanks

Alex, Thanks for the wiki help.
Here is a link to the CXF format stuff.

Did someone rewrite the spec for PID?
