To answer your question: I have no idea.
An alternative though is to just get a DDI subscription, download character builder and then build out your character. When you're done, you can print out a character sheet complete with power cards. These cards will use the stats and bonuses from character builder, thus calculating a lot of things for you, and they will incorporate whatever errata has been released so far (at least, the stuff that's been released and added to character builder). This might be a better option, especially since then you can get cards for powers out of Dragon articles as well. I know it's not exactly the question you asked, but it might ultimately be a better solution for you.
