the major benefit you get from supercropping comes into play after you supercrop, and it will allow more light to get to the budsites that otherwise would be covered by what you just supercropped if that makes a bit of sense..
the smaller, lower nugs get a chance to fill out more, which in turn will increase your yeilds..
and yes, i super crop whatever i feel like.. anything that maybe in the way of another bud site, i will just supercrop and move out of the way...
