IB wing rib only has one tooling hole?

[xCountry22]

Most of the builders are enlarging the tooling holes in the IB wing ribs as per Vans FAQ. Every log picture I've seen has TWO tooling holes for the 710 and 711 ribs.

My 710 rib has only ONE tooling holes. Huh? (not counting the pitot tube hole)

If I enlarge all the 711 ribs with TWO tooling holes how does that work if the root rib has only ONE tooling hole? Why do the other builders seem to have TWO tooling holes in the 710 rib?

No one mentions drilling a hole that didn't preexist.

It's little stuff like this that kills me time-wise. I look at log after log trying to figure it out.

Well drill another one.
