Determining overlap?

How can i determine the degree of overlap a cam has? The higher the overlap, the more the car will surge and buck in the lower RPM's correct? Is overlap the most prominent factor in determining driveabilty?

well, actually it's:

[(intake duration + exhaust duration) / 4 - LSA] x 2

Don't get sloppy with order of operations!
