Hmmm...Interesting question.
So, Ed's answer was pretty good, I'll add a few thoughts here:
AW isn't an ideal guide, True wind is what is needed so that you can
keep the angle to true wind to be constant on
either Gybe, assuming you know what the best angle is.
If you can find polar's for your boat, they will give you an idea of ideal.
As Ed mentioned, VMG is your friend in determining what the best angle
is (especially if no polars are available).
You can experiment in different wind speeds to find a reasonably good
angle for windspeed and VMG.
Here's a good article to get you thinking:

I'm fairly new to flying a spinnaker. I did it last weekend in a race
and I believe I overstood the mark as we were sailing 110 AW before
the gybe and 85 AW heading directly to the mark.
How does one determine when to gybe?
