Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Yes, I was a little off.  The 70s structure was R11 all exterior walls, R33 attic.

Our 1994-95 constructed (and current house) is R30 attic, R19 overhangs, R13 exterior walls, R11 unfinished lower (basement) level. Windows are double pane thermal insulated.  Looks like we could update our attic but exterior wall changes could be expensive due to lack of depth and requirement to remove siding or interior wall board.

All still a lot better than what I expected to be standard in other parts of the world.

Much better than mine and, well, I face the very expensive to upgrade existing walls. (Easy are all done.)  I might pull out the R19 in the one crawl space, spray foam an inch (R-7, plus near 100% leak proof) and put the fiberglass back up.
