It should use the same numbers. If you want the complete list of effects (i.e. other weapons), the DB thread links in my sig will get you them. Those numbers are all empirically tested so that they are correct. You need Open Office, though. You can try out the aoe effects and see what happens. I'm not updating the bug shortlist today anyway, so you have ample time to experiment to see if secondaryeffectalways is bugged or not.
