Stabilizer Rib at 34 1/2"

[Cherrybark]

Looking at the picture in the manual, the horizontal stabilizer rib at 34 1/2" should, or might be, flush with one of the metal ribs. My layout of the listed dimensions has the rib 3/4" inboard of the metal rib. The corresponding elevator rib lays neatly along a supporting metal tube.

I realize the manual drawings might not be perfectly up to date. The stated measurements clearly state 34 1/2" and the ribs are nicely spaced. But, with this wonderful resource of builders, it seems silly not to ask. Am I putting too much into the drawing and the 34 1/2" is the correct placement?

Note, the ribs in the photo are just laying loosely near their positions.
