Tim:
The posted weekend green fee was $95 ... but with discounting in the spring and fall and weekday afternoons, the average green fee was more like $70 to $75. That's one part of the equation that most pro formas forget, and it only makes people miss the revenue estimates by 25-30%.
As to why they only played 20,000 rounds, I suspect that the $95 green fee is too high for regular play for many golfers, and they didn't attract enough rounds from further away due to competition (both from Bulle Rock and from the many newer courses around the south/west side of Philadelphia).
