Hi Guys:

Just another quick question on EOT as long as we're on the subject again:

Is the average EOT correction over the course of the entire year equal to
about seven or eight minutes? from (16+15)/2/2=7.75 min.. As 16 minutes is
about the extreme correction on Nov. 1st. and 15 minutes is the other
extreme corroction in mid Febuary.  Does anybody know the exact average?  

The reason I ask, is that I state in my Sundial Owner's Manual that if one
does not have access to an EOT graph (or doesn't have it almost memorized,
as I'm sure many of you do), then, on the average, if you read the time
directly from a longitudinally corrected dial, your non-EOT corrected
reading would be off by about seven minutes on any day of the year.  (Which
isn't bad as many clocks that I see are off by this much or more.

OR, am I completely wrong; is the average EOT correction equal to zero? 

muchas gracias,
John Carmichael
