This is somewhat accurate depending on the amount of wind you sail in and the boat you sail. In keel boats, when the wind is too weak to get you boat to hull speed, look for wind as this will make you faster than the competition.
Once you're at the hull speed more wind gives you no advantage and then, the angles are more favorable to monitor.
Of course even in light winds you have to sail to the mark so if you get headed 45 degrees, you'd want to tack; even if the wind might be stronger on the side you where pointing. Getting proper judgement on angles vs wind strength is essential.
I'm guessing you do sail keel boats let me know if you don't cause its a whole different story..
