My experience is that the recommended CG is only an approximation and is almost always too far forward. You really need to fly the plane and decide for yourself if it's handling properly.

My opinion is that if you're within 1/2 inch, go fly the airplane. You can fine tune from there.

If you're an inexperienced pilot, it's alway safe to err on the nose heavy side. Moving the CG back to an optimum point, however, will result in the best handling airplane. That can only be accomplished by fly-and-try.

Good luck.
