The idea of precinct summability is that full ballot data is a lot of information, but if you can distill it down to a small list of numbers, precincts can submit their data much more easily, even throughout the day. (right?)
Below is full ballot data for the notorious Burlington 2009 election. The only way it has been "summed" is by condensing identical ballots into a single line, preceded with a number to show how many identical ballots there are.
4.23k of data. (you can zip it down to 1.27k) No that's not 4.23 megs. 4.23 kilobytes. You can fit 340 times this much data on an old-school 1.44 meg floppy disk.
Why are we so worried about this again?
