"You said 27.27%, Alex posted 27.277. Is his added digit meaningful?"
No, it's not. Why don't you just try it out? Also, try the calculation
using 27.24% (that's the value recommended in the Nautical Almanac --not that
that's any reason to prefer it).
You asked:
"How "approximate" is "approximate?" "
Exact enough for lunars. 'Approximate' only from the point of view of an
astronomer.
And you asked:
" "0.14 minutes of arc." Off what standard, please?"
The observed value of the Moon's diameter differed from the expected
value of the Moon's diameter by 0.14 minutes of arc (which is a very small error
--nothing to worry about).
