ivans;
This chart was made for reference material. The shooter's physical dimensions provide information to the stocker, because of experience and conversation with the client, providing an accurate starting point in which to build a stock.
The factory dimensions are listed in the chart for starting reference points only. Stock dimensions can be changed depending on the whole chart. I guess the best that can be said is that the chart is a tool not a crystal ball. Experience in fitting and shooting helps the stocker identify potential problems and seek solutions to them.
Since you are an idividual unique and special, your stock will not be the same as the one I need.
If you are refering to the medical anatomical science of proportions,in relation to fitting a gunstock, sometimes it works and sometimes it doesn't. My measurment from finger to elbow is 12 1/2". I shoot rifle at 13 5/8" LOP and Shotgun at 14" LOP. If you followed the strict rule of anatomy I should shoot all guns at 12 1/2" LOP
That rule doesn't hold true for myself. In some shooters it does. I am not the exception to the rule. The factory European shotgun LOP is usually one inch longer than the American LOP. Most Americans are rifle shooters and shoot their shotguns the same way. The style of shooting does make a difference in how the chart is applied to stock dimensions. The physical dimensions help identify special needs to consider in building the stock. All factors are put together to make a complete package. The proof of success is a happy client.
