Well it's just a ratio between air inhaled vs. displacement x revs. With other words, if your 3.0L engine turns at 1000 RPM, it will "inhale" 25L of air per second in perfect case (3L x 1000 times a minute / 2).
If you measure the actual flow and it happends to be 23L then your VE is 23/25 = 0.92 = 92%
Now if it inhales more air than it theoretically chould, then you hit the sweet spot. (In reality, you will need hi-end 4-valve engine with straight stacks and evil cams/headers to even try this stunt).
