I use the Boone & Crockett and/or Pope & Young method, which are the same. Measure all thetine lengths,main beam circumferences andmain beam lengths (as per the book or score sheet instructions) - and add the number of inches on the inside spread of the rack. And there is your "GrossScore".

Nextdeduct the difference (in inches)between each measurementon each side - and get a new total, which is your "Net Score".

Many people are "off"by a few (to several) inches when they look at a rack - or a photo. So, you will end up with a wide range of scores ...
