Math double-check

I've written a thing for an upcoming PokerNews article that involves a lot of math--not highly advanced, but moderately complex poker probability stuff that can't be looked up online. I'd like to have any embarrassing errors discovered before it gets published, rather than after.

If you're reasonably good at figuring out probabilities using the formula for card combinations, and you're willing to spend what I think would be 30 minutes or so looking over my work, please let me know: submit a comment below with "do not publish" or words to that effect, and your name and email, and I'll send it to you for a look-over.

Thanks.
