I've reduced many sights with the Ageton method on a blank sheet of
paper without referring to any instructions. It is not difficult if you
stay in practice. I think any expert celestial navigator should be able
to do that (including all the corrections) with his favorite reduction
method. The steps should all be so familiar they can be performed by
heart without the prompting of a form. (But a form reduces the chance of
a mistake.)
