Come on Alex, do I quibble about your 0.0 error averages with 1.0 SD's ;-)
Of course you have the excuse that your sextant only reads to 1!0.

What can I say?  Sometimes I am happy to have one in the win column, even it
was not a pretty win.

I too trust the sun IC's over the stars.  I am very bad at star IC's. I am
not clear that sun IC's are preferred over natural horizon checks in my
texts.  My interpretation is that sun IC's are am alternative method,
especially suited for those of us that are landlocked.
