[squid-users] Strange hit ratio output from mgr:info

This is from a 64-bit 2.7STABLE6 instance, as part of the squidclient
mgr:info output. We're seeing values similar to these on every squid
we operate.

         Request Hit Ratios: 5min: 97.7%, 60min: 97.3%
         Byte Hit Ratios: 5min: 93.2%, 60min: 95.8%
         Request Memory Hit Ratios: 5min: 1.5%, 60min: 21.3%
         Request Disk Hit Ratios: 5min: 30.3%, 60min: 40.0%

Unless there's a subtlety I'm not aware of, I would expect that the
values under "Request Memory Hit Ratios" and "Request Disk Hit Ratios"
to add up to the overall "Request Hit Ratios" percentage. Are there
types of hits/misses (for example, near hits possibly) that don't get
put into these percentages? Or another explanation for this?

Thanks,
