You ought to have a very good idea of your distances with each club. Create your own distance chart.

You’ll make better club selections with your own table. You’ll under-club less often because you’ll be much more aware of your "usual" distance with a club.

We often hear a wind described as a one-club or two-club wind. But the actual impact on distance is more significant with a headwind than a tailwind. Golf Digest tests showed a particular wind speed taking 17 yards OFF the distance on ball strikes into the wind. When the wind was behind the golfer, it only added about 66% of that.
