I looked at the effectiveness of this test and I like what I'm seeing. The volume isn't high, but it is making a difference in the "edge cases" that are close to my "hold weight".
In particular, I'm finding that it is triggering on pump and dump DKIM spam from fresh netblocks that would otherwise leak into my mailboxes. Some of those also trigger SNIFFERSCAM. So if you don't trust the global "truncate" test alone, it's a good test to combine with other weighted tests. P.s. I'm also finding that truncate is triggering on email from some ISP users when I check multiple hops in the header. That probably means that I'm finding users with zombie infected computers, but I'm letting that mail in, so checking which IP addresses were hit is a small problem if I want to contact those people.

We have decided to experiment with opening up the blacklist for a wider audience and so as of now you can use truncate.gbudb.net as an ip4r test. You should get a result of 127.0.0.1 if the IP is well into the truncate range -- That is: truncate.gbudb.net is designed to be ultra-conservative so that it should be safe to reject connections based on the test in most cases. This also means that it won't block everything -- only the worst of the worst. That said, the folks who have been testing it have reported that it did drop a significant amount of traffic from their systems on average. Please keep us all posted about how it's working for you.
