"Haynie hopes average rounds can ultimately be less than four hours, instead of 41⁄2 to five as it is now."  I assume this is meant for recreational golfers playing in in a foursome, fivesome, or sixsome and not for men and women pros playing only in twosomes or threesomes in a golf tournament?  Also your score depends on how much you know the rules of golf.  The less you know, the better your score will be and vice versa.
