For the record, I've shot 17 lunars in the last month AT SEA on a ship of
various bodies and in various conditions (including rolling 20 degrees) with a
cumulative average error of +0.26 minutes of arc. Each of those lunars
aveaged 4-7 sights each.
With modern reduction techniques (read computers) it takes a matter of
minutes to reduce the sights. I am certainly more confident of both my
determined index error and my chronometer because of my lunar work.
