Webs OK as they are.

In other words, to have an actual 2G load capability for the box-stock wing, do the existing webs with the holes, have to have web doublers to make them solid? Were the web triangle cutouts figured in the calculations? I'll definitely add web doublers, but It just makes me wonder if the webs hadn't had those large cutouts for assembly, if the wing would have failed so easily. Thanks for all your time and work.
It should do the 2G with the out of the box wing. The cut outs in the Webs are OK. They should still carry enough shear between the spars as they are as long as they are glued fully to the spars. This is important as the provide stability and prevent compession buckling.
This is still a perilously week structure though.
