identifying the slow check

Actually, this is very interesting. I found and killed my slow check
(a fping, as someone else suggested). Running the profile script
below gives me:
Total Execution Time: 47 (sec) NumChecks: 144 Average Time: 0.332 (sec)
>From reading status.dat, this is about what I'd expect.
On the other hand, the "Active Service Checks" in the Web interface
shows very different numbers:
Active Service Checks:
Time Frame Checks Completed
<= 1 minute: 44 (30.6%)
<= 5 minutes: 144 (100.0%)
<= 15 minutes: 144 (100.0%)
<= 1 hour: 144 (100.0%)
Since program start: 144 (100.0%)
Does the Web present a long-term average or some such?
Thanks,
