Agreed, but I was offering to check his work with Navigator Light and see
what it offered up for Hc and Zn. I know you can do that by plugging in
various values until it all works out (essentially working "backwards" to
find the time given an assumed position), but I really don't have the extra
time to run through all the iterations necessary to do that...  ;-)

See above - and agreed, I could duplicate his calculator work but I'm
assuming he did the math right.
