I love the high percentage implied by the figures, that got all of Port noise com play aint and simply weren't any the wiser. But you have to be a certain age to have even heard of it (it was published when I was 8), and as far as I know it has never been adapted for the screen.
Once people heard it was banned for obscenity in several countries, of course everyone wanted to read it. Richard Benjamin also starred in the film adaptation of Goodbye Columbus, another Roth book.
Maybe add some different spellings for Cassie. I tried every single spelling I could think of except for that one. I have several friends who are named Cassandra and none of them shorten it to Cassie. Maybe accept "Casey" or "Kasey" or "KC"
Not that I expect to hear it often, of course . . .
