Beats me...more likely, there is some sort of SKU-equivalent info
available to the firmware and a table of predefined regulatory rules
mapped to those SKUs.  This, of course, does nothing to prevent
situations where one is using values that are OK in your country of
origin but not in your current host country.  But I suppose that is
more of an import/export problem...?  Whatever.

Me too.  If/when I find a way to alter time or speed-up the harvest
(or teleport me off this rock) I think I would enjoy working on that!
In the meantime, I hope someone else with applicable skills and
interests takes that opportunity.
