That's sufficient.

I ask because the % statistics gets very sensitive when there is very
little load (no active users).

It's normal that one or two requests every now and then uses a little
more data than what is delivered to the client. This comes from 3
factors

  - quick_abort_* settings allowing continued retreival even after the
client have gone away. Plus if clients are low bandwidth some internal
buffering as well.

  - range_offset_limit when configured

  - automatic retrial of requests in certain normal error conditions.

If traffic is ver very low then one or two requests in these categories
can easily make negative byte hit ratio. But it's not normal if you have
users actively using the proxy at the time.

Henrik
