I have been following this also.

I am wondering, don't the narrow bands only read stoich.
Can the computer compensate for the difference in commanded?

When I get a chance I will do some logging to see the difference but it seems that even if you command 14.37 that the narrowbands will still look for 14.63.

Or I may be way off base. Do the switchpoints make that difference in the stoich points?

Any insight?
