Performance Monitor - Apache Processes/threads?

Hi all

Im using perfmon and the % process time counter to monitor apache process
CPU utilisation, but I am having trouble interpreting the figures...

I have captured data on the following processes:
apache, avg=0, max=0
apache#1, avg=173,max=199
apache#1#1,avg=173,max=199
apache#1#2,avg=87,max=100
apache#1#3,avg=12,max=826
apache#2,avg=87,max=100
apache#3,avg=12,max=826
apache#4,avg=0.11,max=0.625

So, from the stats I can see the #3 actual equated to #1#3 (for some strange
reason). What is confusing me is the value 826, I thought the max % was
100, so this value is right from left field and I am not confused what real
%utilisation I am experiencing from apache??

This confusing increases with the values 173 and 199, how I work out a final
% of 100 for apache is beyond me.

Thoughts?

Cheers
