Hello,

The software I plan on using for the eclipse (Set'n'C) has an option to use either automatic or manually entered delta T.
I noticed that the most recent delta T number I could find is a bit off of the automatic one that the program has.

My question is, how far off of the correct delta T is too far off. I am worried about running into problems if the automatic delta T turns out to be too far away from the actual.

Thanks for your help,
