I agree that SGC and GAI pops should be combined with PSA.
I don't agree with the following:
1)I do not think there is much high grade pre-war material that has not been graded. By high grade I mean nrmt-mt or better. I have found that most collectors who think they have nrmt-mt cards or sets don't--at least by the standards of the Big 3 grading companies.
2)To the extent that there is more than I am estimating, the sample size is large enough for most of the popular pre war sets(and all of the popular post-war sets) that the distribution of newly graded 8s and better is likely to be similar to the distribution of those already graded. Thus, the cards that are condition rarities today are likely to be the condition rarities tomorrow.
Regardless, the market is telling us that pop is the key driver of pricing in vintage graded sports cards.
