please help me make sense of top's CPU output

I recently performed a CPU intensive task with Xorg. When I completed the task and Xorg no longer was using the CPU, I got this result from top:
last pid: 1201; load averages: 0.24, 0.10, 0.09 up 0+00:29:42
63 processes: 1 running, 62 sleeping
CPU: 1.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 99.0% idle
Mem: 161M Active, 67M Inact, 68M Wired, 1240K Cache, 41M Buf, 1676M Free
Swap: 4060M Total, 4060M Free
PID USERNAME THR PRI NICE SIZE RES STATE C TIME CPU
1017 cstankevitz 1 104 0 366M 331M select 0 3:25 35.89% Xorg
Note that the "CPU" row reports 99% idle.
Note that the "CPU" column reports 36% Xorg
I have two questions:
1. Why do these two numbers seem to not agree? One reports the CPU is not being used, the other reports Xorg is using the CPU.
2. How can I change my system so that these two numbers seem to agree?
PS: conky does the same thing -- I assume this means the seemingly disagreeing numbers are coming from the FreeBSD kernel.
