That's true, but it's still working in a book, looking at small numbers
inside a washing machine while drinking a tuna shake.

You're right, you should be able to do better. It's just a problem of
when you can do better and when you can't. If you're unlucky, when
you can't will be when you need it.

Yes.

It's also tedious to do the numbers.

No, not unles you venture into lunar distances or trying to do it by pure
math. Using H.O. 249 or doing noon hights is not that complicated.

But, I agree, it's worth knowing. Then, when you miss Hawaii, you can
say
with certainty... well, I only probably missed it by 60 nm.

You have a point. Celestial navigation on a boat does not have the
accuracy
that we get used to from GPS, but I think you should be able to do at
least
10 times better.
