Finding your Speed Drop Factor

How long does it take to find our drop data for a target range?  If we need data quickly, most shooters are using some type of paper chart. This chart could be taped to the stock, on a data holder, or arm bar where with a quick glance we can read our data.  What if there is a faster way?  Welcome to the Speed Drop Factor.  Finding and using your Speed Drop Factor will allow you to memorize your drop data to a reasonable distance by remembering one number.
