Hi Chevron! I was curious about the same question so I did some research. When I compared your awards to your score history, the following matched up:
Bronze skill challenge cup for Bali Hai
2 Silver skill challenge cups for Wk 22 Kiawah and Wolf Creek
Data from your score history:
05.28.09 Wk 22 Bali Hai Closest-to-the-Hole Sweeps Amateur 502.06
05.28.09 Wk 22 Kiawah Closest-to-the-Hole Sweeps Amateur 342.89
05.28.09 Wk 22 Wolf Creek Closest-to-the-Hole Sweeps Amateur 459.37
I don't have the exact information, but I'll make an estimated guess. The Closest to the Hole Skill Challenge cups are awarded as follows:
Bronze = scores just over 500
Silver = scores between 250 - 499?
Gold = scores between 150 - 249?
Platinum = scores between 100 -149
Crystal = scores between 50-100?
Diamond = scores under 50?
Hopefully this information is what you were after. I believe the torunament cups are for placing in the different events. I'm kinda new here so this info is vague. Maybe someone else can shed more light.
Until then - GL on the golf course!
