In addition to forgetting to roll up the false alarm counts, I also realized that the hourly averages were probably wrong because there would be hours in which no medical/fire/false calls happened; those zeroes wouldn't be represented in the data when the mean was calculated. I changed it to a sum and divided by the number of days in the 7 year period (365 * 7 + 2); fortunately there are the same number of hours in each day.

The data have been passed on to Merritt, so this is just for posterity.
