One observation I have is that a number of people didn't get counted because they were one, two or three blocks over. With a school in the area many pedestrians took the most direct route. Plus experienced (I assume) cyclists wanting to turn left from southbound Post onto Buckeye made the turn a couple blocks beforehand and then popped out onto Buckeye a couple blocks down the road.
