Default RE: hybrid wing problem

So by now im thinking to myself *** is going on. I then decided to take center line measurements of ALL the ribs. Here is my findings. I am measuring in MM for accuracy.

R1 - LE 53mm TE 54MM
R2 LE 50MM TE 49MM
R3 LE 46MM TE 49MM
R4 LE 43MM TE 46.5 MM
R5 LE 40MM TE 42.5 MM
R6 LE 38MM TE 40MM
R7 LE 36 TE 36.5MM
R8 LE 32.5MM TE 34.5M
R9 LE 30.5MM TE 32MM
R10 LE28.5MM TE 30MM

I realize that we need to allow for a little warping in the balsa and for the most part, all of the ribs are within 2MM front to back but you can see that something is wacky in R3,4, and 5. Not sure how to handle this. The only way I can get all of the center lines to be the same is if I begin reshaping ribs or cutting notches in the template. None of which are desireable.
Sooooo. Any idea on what may be going on?
