Taking weight off a cue

A while back, someone had posted somewhat of a formula for determining how much of the weight bolt to cut off for each ounce you want taken off of the cue.

Does anyone know what that is? I'm looking to take my 20oz down to 18.5oz. Thanks in advance!

Depending on what cue you have, it will matter how much to cut off. With the standard weight bolt, such as the Predator and Lucasi, every 1 inch equals 1/2 oz.
