I'll find out if you are right.  I haven't figured much on a machine. I
didn't do as well as hand figuring but then I didn't know anything then. I'm
sure you are right, so I will have to have a navigator with me the next time
I try machine figuring so I can find my way home.

In some cases I agree, especially with hand figuring on "normal" Newtonian
sized 
ATM primaries.  The 8" F/8 bino mirrors (my first optics) figuring was as
you 
described, and almost a non event. Several 10 inch F/5 to F/6 also were very

intuitive.  However when the first 12.5" F/4.5 found itself on the machine, 
intuition went south.
