OK, I just brought up the geistware application to see if anything I told you above was actually true. Old age sometimes dims memory, and I haven't looked at that application in over a week soooooo.......... chuckle...........

The measurements go in the light purple box with your desired SM. The "tell me" button is in that box too. Nine easy to do measurments and your desired value for SM.

When you hit the "Refresh MAC and Neutral Point" button, almost all the other purple boxes' blanks will be filled in. You're really only interested in one answer, and it's in the box that's two shades darker purple. Calculated Results is the heading. And the answer is in that box. It's the measurement in inches of the CG back from the LE of the wing at the root.

hope this helps you. it helps me.
