rawstats needs some work

Currently, it only records packets that are actually used.

I'd really like to see packets that are rejected because the round trip time is too long.

It would be nice to see packets that are dropped for other reasons. We have to be careful to avoid DoS due to trying to log too much garbage. Something like log 1 response per request sent would be OK. Maybe 2, 1 bogus one and 1 that got accepted.
