Dean bat over time

Has anyone been tracking the hourly updates over time?

I am very curious as to the curve of contributions.

e.g.:

1. It looks like the bats start slow and finish fast.
2. I think that weekends are slow days, weekdays are much faster, holidays slow.   Which begs the question, are people donating from work?  Or after they get home?
3. Is there any correlation between certain events and bat speed?
4. Do "attack-response" bats fill up faster than end-of-quarter bats?  
5. It would also be neat to compare bats over time, starting w/ the earliest and moving up to the most recent.  Interesting indicator of the strength of the campaign's growth.

These data would help predict that bat movement somewhat, but would also be foiled by behind-the-scenes manipulations like when the staff decide to type in mailed/houseparty checks, etc.
