You cannot make conclusions based on a few random rounds.
Well, of course I can!
Based on Ben Crenshaw's rounds alone, I can conclude that, contrary to the received wisdom of recent days, a relatively short hitter can, in fact, compete at Augusta National Golf Club!
I may not be able to draw scientific conclusions about the question you consider important -- but that is not the question I was pondering.
Now as to your question:
The question, you say, is: Does Augusta National "disporportionally" favor long hitters.
What does that mean? Does that mean: Does Augusta favor long hitters more than OTHER courses favor long hitters? How many courses are you aware of that don't favor long hitters?
Or does it mean: Does Augusta favor long hitters more than it *should* (whatever that might mean)?
