Note the text "as % of hit requests"

So...

cache hit in mem = 51.7%
cache hit in disk = 31.8%
cache hit in other (peers? refresh?) = 100 - 51.7 - 31.8 = 16.5%

miss information completely unknown.

Disk won't get 100% used unless you make your cache too big for the
drive, or screw up cache gargbage collection with the cleanup settings.
