I just checked our statistics, we have seen 6.1% matches since September 
13th. I haven't yet analyzed, if we see something similar. I rember that 
our match percentage was lower - could it be that spammers are starting 
to queue? I try to find time to see those logs more thoroughly.

Now that SJSM offers Milter interface, it would be possible to demand 
that every message individually should be tried second time. That is, to 
calculate the hash from the whole message, not just the triplet. Of 
course that means more network bandwith would be wasted.
