Thanks Oscar You were mostly right, I was trying to simulate the addition of the passenger weight by weighing the tail and adding the remainder of the weight to the mains, except I added the weight to the seat and not the mains. When I reaccomplished the exercise with the weight on the mains, the CG stayed within .2 of the location that I used in my spread sheet for a passenger datum with the total #120 added. Thanks Kevin PS Flying was good today, I did not do any testing due to winds of 10 kts and 90 degrees.
