A small correction: measuring lunars WAS a means to an end (establishing
GMT), a long time ago. But nobody loses GMT anymore. Today most people use
lunars to test their sextants and their skills. In that case, the final step
is calculating the difference between the cleared lunar and the predicted
lunar at a known instant of GMT. One could also use them to get lunar lines
of position, as I've demonstrated several times.

I think it's important to remember that shooting lunars for GMT is basically
a sort of antiquarian game --a form of historical reconstruction. And
different people will have different rules for this game. Even one person
will play the game differently at different times. Sometimes we apply modern
solutions to the historical problem. Other times we try to use the original
methods and tables. But in the end, there's no one way to go about it.
