Every word is quoted in an e-mail from Kevin to me except what is in the parenthesis which is my editorial comment or explanation on what Kevin is saying.
It is much easier to get a lower grade into a mid grade(my exact point) or get a bump(on a low grade) and one can probably do it every time. Like you mentioned, there are more problems that need to be fixed, its easier to cover up and more leverage. Even a good soak can give a card much better eye appeal, enough for a grade bump.
I do think that on a percentage basis alone, there are more altered cards in 7 and above holders. Its much more difficult, requires some skill, but is by far more rewarding.
My view for prewar alterations
2-3 through 6--higher volume
7 and above--higher percentage
Postwar--a wash.
My comment--this all makes sense to me--more lower grade cards have been altered prewar but a higher percentage of higher grade.
