I always forget that libraries share stuff like that. Good luck, and I look forward to seeing it! I'm sure the IHPVA has some stats somewhere too, but I don't feel like rooting through forty years of PDF's to find it.
As for tucks... for me it's a comfort issue. I'm much happier on flat bars than in drops. But by all means, if you're comfortable in a tuck, go for it. It's also nice that bicycle "fuel" is much cheaper than gasoline.
