how many squares I could get with no form of bingo at all, and then at the end I'd rec like 2 or 3 things and get 12 bingos out of it. That plan did not pan out!

LOL! A good plan, though. And as it's worked so well, at the moment I am vaguely planning to do it as the regular summer challenge, or certainly, at least to run it again sometime - so, next time!
