At first blush incorrect incidence of 1/2 degree and 12 clicks of up does not sound reasonable. Just how far off is the CG?

At every club there will be a few masters at trimming. Although I have flown for a very long time it is still helpful to occasionally have a trim master fly one of my airplanes. Two heads have a better change of catching a problem. Something new is always learned. It is remarkably easy to overlook something simple.
