I?d say about 500 of the 20000+ rivets needs help.
I am almost done and have almost exactly 2100 hours of my own time in the build. There are 50-100 additional hours by others.
spending most of my time trying to find where I put that tool I just used 3 minutes ago
Be careful when you teach her how to rivet.
It may end up costing you another $100K. (She might want her own.)
