You can't find it? Did you possibly delete the man pages from the system? Or just that one?

Code:
%CPU  --  CPU usage
          The  taskâs  share of the elapsed CPU time since the last screen update, expressed as a percentage of total CPU time.  In a true SMP
          environment, if âIrix modeâ is Off, top will operate in âSolaris modeâ where a taskâs cpu usage will be divided by the total  number
          of CPUs.  You toggle âIrix/Solarisâ modes with the âIâ interactive command.

Copied directly from the man page on 'top'. It is the second section of the man page, specificaly 2a "2. FIELDS / Columns - 2a. DESCRIPTIONS of Fields".

Just testing really quick on a CentOS 5.2 box, using top cd1 I noticed something at between 80 and 100 on cpu. So I did shift + i (capital i), and it turned Irix mode off (apparently it is on by default), and then it showed the usage of those at about 12% or so. Yeah..

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
       on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more  informa-
       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
	      The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
	      Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
	      This  is	the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
	      configuration file.

       -V, --version
	      Display the version of the software.
