Ryan,
This should probably be a whole new topic in another thread, but without going to far into it I will try.
I cannot speak for clubs in the UK as I am not experienced with managing turf there. I also cannot speak for other clubs other than ones I have worked for without spending the time to get a true understanding of what it takes to maintain them correctly. This is a process and there is not a template for putting together a maintenance plan for any course as they are all different. There is so much variance from place to place ranging from members expectations, climate, budget, amount of bunkers, bentgrass vs bermuda greens, style of course, acreage, shade, water restrictions, air movement, the list goes on and on.
It is unfair to say well this club has 150 acres and they have 5 guys on their crew why do you have 20? You must compare apples to apples.
