Make the mark

I would like to hear the tricks and techniques folks use to determine if they are on the proper course to fetch the desired mark.

Tonight I was headed towards a buoy and was surprised when I compared the gyps course to the compass course and noticed that they were about the same.
I was traveling upwind but the current and wind slippage were in opposing directions and cancelled each other out almost exactly.
Doesn't happen that neatly too often.

Hear is what I've been doing?
Hold a steady compass course for a couple of minutes and see if the heading to the mark moves.
Try to estimate the current and wind and do the trig in my head. I know some shortcuts.
Of course the simplest if you want to use the gps is to just keep the heading and course numbers the same.

I find that with the variation of wind speed and currents even in short legs of a couple miles or so it is easy to misjudge especially if the mark is upwind.

What tricks do you have both gps and non-gps?
