Sorry but that's nonsense, try telling that to a Planning officer, they look at you like your mad! when I was running sits I generally estimated that you got one decent site a year, the rest were not worth doing and never even proceeded to excavation, ie a tiny percentage. We need to collate figures and figure out just how much were doing and then figure out how much we should do and accept that some archaeology will be lost!
