There is all sorts of good stuff to confuse the newbie. Here's my theory. I use a $35 watch I got at walmart. Every week or so I check the time and if it's within a second, I go with it, if not, I re-sych it with the time tick. I never worry about rates beyond the fact that I have to adjust it every month or so at sea. If you are within 1 second of time, you are in good shape with Celnav for practical considerations. Unless you are observing with someone else recording it generally takes the better part of a second to pull your eye from the scope and look at the watch (which only reads in whole seconds anyhow). So I usually note the time and subtract a second during my observations. (Although that 5x datascope at Celestaire certainly has my interest if it works well). My observations are often under 1 nm and only very rarely over 2 (and that is because of horizon issues not time). I must also say that it was amusing to me to see all of the radio jargon earlier in the thread. I should have known there would be some Ham types on the board.
