Wing incidence & other measurements

My fuse is lat. & long. level; the leading edges of the wing are <1/8" of a straight line; measurements from like points on wing tips to rear-center fuse is within 1/16". I'm satisfied with these two measurements.
I am setting the "very-important" wing incidence. With the level placed near the root end of the wing, and zeroed-out with the 3" riser positioned per instructions, I get a difference of 0.4 degree near the end of the wing. In other words, the trailing edge at the end of the wing needs to come up 0.4 degree to level-out. I have QB wings. It would "seem" that there is a very slight twist in the wing. (The other wing is out 0.2 degree.)
Is there a fix for this? Should I "split the difference"? What have others encountered in this measurement?
Am I being too nit-picky?

I have my drill in hand with finger on the trigger at the rear spar attach point.

Thanks for any advise on this.

I saw the same thing in my QB wings although mine were the same on both sides at (I think) .2 degrees. Vans said to set the incidence with the level/spacer at mid-span, essentially splitting the difference. I think we may be being a little nit-picky but hey, the QB's should be right on shouldn't they? I was a little bummed by the fact that the twist was a "wash-in" (greater angle of attack at the tip) direction instead of wash-out. Sounds like yours is the same but again, I don't think the magnitude is enough to worry about. As always, call Vans directly if you are unsure.

Hope mine is that good. Drill it and move on!!!

You're right Charlie...I did and....I did.
Here's Van's response FWIW;
"We don't have a tolerance on the wing incidence. I would split the
difference and get them as close to each other as I could. Average
all the readings out and go from there."

One additional note here: There is a PDF file on Van's website that explains setting wing incidence in more detail than the regular instructions. I suggest that you use it.
