%icap:: codes are relevant to ICAP.

%adapt:: codes are relevant to all adaptation types: ICAP, eCAP, and (in 
theory, though often not really) redirector and URL re-writer helpers.

NP: failed transactions timers are included in all three metrics.

AFAIK you are right - it is supposed to be the sum of all processing 
time for ICAP related things.

It does seem to be a bit odd that only the first one ("4") is counted. 
Likely a bug IMO.
