Need help with the wing incidence on the Hawk

I am setting up the wings on the Hawk and the top wing is at 3 degrees negative which seemed excessive I checked with GP about the Top and bottom wing incidence and was told the Top wing should be 1/2 degree negative and the bottom wing to be 2 degree negative. My top wing assembled shows about 3 degrees negative and will have to be shimed to get the 1/2 degree negative The bottom wing is OK All the struts are installed correctly. Have any of you that have built this plane had the same problem. Would appreciate any comments and advice. I am using the Robart incidence meter for set up

Thanks
