It is amazing what clecos can do to pull a skin, sometimes this is good, sometimes it can not be so positive. I think as you go along, with fluting ribs and clecoing you will notice that when you get the fluting right, the clecoing is effortless, and that sometimes you struggle a bit more to get it tem all set. This comes from that ever so small non-linear line of holes in the flutted rib, the skin holes are flawless of course in alignment. Have fun as you build, what a great project the 10 is!!
It's funny that you posted this now. Yesterday I removed the horn and fluted the two horn ribs as you said so that the holes were in line. What a difference it made for the fit as you said. It squared everything up nice (I measured as you described). Up to this point I was a little apprehensive about fluting but it really is quite simple and satisfying, and it made a huge difference.
