Sometimes ya get lucky! It might be fun to try this ten days in a row and
see how well it works on average.

And:
"I haven't tried this type of sight myself but was always a little curious
to try it."

Supposedly, Nathaniel Bowditch himself experimented with these sextant-free
sights on his first ocean voyage in 1795 but abandoned them. In his case,
though, I think he was trying to observe the rising and setting of stars.
Since he had never been to sea before, he apparently did not know that this
was basically impossible. And since they had no chronometer, the value of
these sights was minimal anyway.
