If you are just going by the geometry of things, it doesn't matter if you make one tack or ten. In reality...you have to consider wind trends and shifts, and that you'll lose some time during each tack even if they're done perfectly. And covering the fleet (assuming you're racing?) and all the other tactical issues.
You might want to check for articles online (or, gasp, in print) and then do a gut check versus the pro opinions on what's going to work best for you.
