There is this info on R value -- valid (?) --

I would say that is a pessimistic approximation. It might be what theory suggests, but is not what happens in the real world.

I have lived in too many houses at different levels of R-value in walls and ceilings to accept that table as "truth".

Tell the people in Alaska that there is so little difference between R-19 and R-50 in their attics that they are wasting their money. They won't buy it, and neither do I.
