Even though the static CG is right on the recommended mark, the dynamic CG may still be nose-forward, as Metallica suggests, leading to a quicker landing speed. GP recommends a setup that is very conservative and 'safe'. Try flying the 1/2-3/4 throttle inverted 45* upline hands off, and see if she curls toward the horizon a little or none (good) or a lot (nose heavy) and make small adjustments to your CG from that info also.
