j4sN: I don't think you understood his question.
What Valshar was asking was, if he spends his SP points without leveling his mastery, would it effect his SP farm rate. The answer is no, it wouldn't.

if your sp farming you should leave a 9 lvl gap.. highest mastery 9 lvl away from current lvl.
The amount of gap is really whatever your preference is. Some people prefer a 4 lvl gap, some prefer a 6 lvl gap, and some vary it from 4 to 9 depending on what they need and feel like doing. But, of course, a 9 lvl gap will give you the best return on SP points.
