It strikes me that theres a variation of cant...Both quantity and quality some shoots you get a bit of cant and at some shoots you get lots of cant....Perhaps theres a formula that can be derived to calculate aproximations of cant per shoot..
Therefore
Cant =( number of shooters/0.3414525) / (weather factor*course length)+ number of targets*neil hagues hair folicles
Something along those lines but we could do with someone cleverer than me to confirm this equation will work.
