You pretty much just have to get 97 to 98% on these maps in order and as they start giving less move the stars># up by .1; if you're finding these too easy and can SS them just move up .1 until you start to get inconsistent. Just a word of warning, .1 is a big difference so try not to get cocky and move it by 1.0 or .5; you're gonna get wrecked. Just keep trying to maintain that 97-98% on maps in order.
Everything is so simple now; new players just need to figure this out.
