I'm sorta (but not too) surprised I'm so far off. My only real sense of what a grade looks like is from what other people tell me- like this video of biking up Fargo Hill in LA (claimed to be the toughest hill in North America with a 32% grade for over 1/10 mile).

That didn't look too much more terrible than the top end of Buffalo St. to me, so I was basing my estimates on that. Guess I'm not so good at estimating
By 366 in Varna (heading into Cornell) I mean the Hill between Forest Home Drive and Game Farm Road, near the Varna Auto Service.
Thanks again. I think that this sort of info might be useful for novice cyclists trying to plan which routes to take around here. For instance- I was debating trying the climb into campus via the bike path on 79 as opposed to University Ave (which is too frequented by speeding students and potholes for my tastes)- but I think the 79 route would get much worse once you turn onto 366.
There isn't any compendium of grades, and such info is actually pretty hard to pin down. Most routes vary a lot in pitch so you can select brief bits of whatever grade you want to attach to the climb. In general, though, your estimates are way over the top.
Probably the best way to get realistic numbers would be to go out with an inclinometer. There's a common, cheap kind that is nevertheless very accurate. It's a simple calibrated bubble device (like on a carpenter's level) that you clamp on the handlebars of a bike. I have one. You have to stop the bike to get an accurate reading, but it's easily good to within 1%. Maybe we can get a measuring group together some day to ride around and record some data.
Looking at topographic software is another way to get grades, but I really don't think it's a very reliable feature. But just to put your estimates in some perspective, let me give you the numbers I get in Delorme TopoUSA.
Buffalo St: lower end ~11%, just before Eddy St. is the max around 16%
University Ave: coming up from Linn St, it's only around 5-6%, peaking around 7% at the corner. Turning east (toward the Johnson Museum) is the max, 11%.
I don't know what you mean by 366 into Varna, but there's certainly no pitch like that on 366. The generally acknowledged toughest climb in the are is Blakeslee Hill Rd (it actually has bits that show around 20% on the software).

Whenever I talk to friends from out of town about biking up the hills here they ask me what the grade is. I guess that buffalo would be about 25-30%, University 10-15%, and 366 heading into Cornell from Varna 20-25%, but I'm not really sure.

I dont know where the funding would come from but T-shirts might be a good way of spreading the commuting by bike message.
