I've been playing in the Top 5, 10, 20, and even Top 30 sandbox for a couple years now.
Seems to have the most opportunity there when looking at strokes gained in relation to golfers skills on certain courses...like the Harman bet I put in this thread.
Seems like I often end up on a golfer that either goes lower than anyone in a round or shoots the lowest round, even if he doesn't cash for me.
Not unlike Harman this week.
