I have No explanation.  Care to send me the Zemax files from step 1 and step
2a.  You can send them to me as attachments if you like.  I would rather
have the actual Zemax files because the difference may be a subtle setting
somewhere that would not be obvious in a prescription output.

The difference between 0.84 and 0.86 is not a lot but it would be nice to
trace down what is happening.
