That's kind of odd, though, considering there are two numbers in a runway number and three in a heading. Aren't you better off setting it to your compass?
Its more a cross-check to make sure that the DG is working, i.e. turning, (since it should have turned when you turn onto the runway) rather than actually setting it to the actual heading (which most people do before starting taxi or at the run-up). Although if it's slightly off (happens a lot on older DGs) you can get a quick rough adjustment before takeoff so at least you're not 20+ degrees off.
