Unless I'm very much mistaken, it appears that a large percentage of the failed BCP 38 spoofing tests listed in that data are actually due to customer side NAT routers dropping packets...
which is of course egress filtering rather than ingress filtering, and thus doesn't actually apply to our questions.
