DCR takes into account you're valve timing, when the intake valve closes on the compression stroke. The later the intake valve closes the lower the DCR, the cylinder doesn't actually build compression until the intake valve closes on the comp. stroke. With a small cam you can't run as much static comp. as you can with a longer duration "big cam". DCR is the compression figure you should really be concerned with.
