What happens if the IAC count is lower?

When I had mine set to ~10 my idle screw was backed out almost all the way and my idle would be too low on cold starts, in fact it was hard to start. With the idle screw turned in a little more it idles much better but my IAC count bounces around 0 to 4. This seems to work better for me, just wondering if it's right?
