As far as I can tell - both by studying the source code and by running "sysctl -x kern.cp_time" in a loop - kern.cp_time increments continuously. statclock() increments the relevant element in the array by one at a rate of stathz (128Hz by default). Obviously, you need to smooth the result over a period substantially longer than 1/128 second to get a useful result (unless you want to pulse-width modulate your display) but 12.8Hz (stathz/10) would give you 10 samples which would be ideal for a 10-segment bargraph.
