Cracking (or shimming) the unisons is a way to move an entire unison up or down a very slight amount for fine tuning. Lets say you have a 3rd that you want to be just a tiny bit faster or slower. You mute out one string of the unison and leave two open. You move one open string so that the two strings have the slightest whine or out of phase sound and then bring the other one up or down to match it. Then bring in the third string.
