Same here. Using it this week and on Thursday I began to understand why Lee Sedol retired not long after being defeated by AlphaGo. For the stuff I'm good at, 3 months ago I was better than the models. Today, I'm not sure.
Amazing to see the scale of it. As a piece of feedback my assumption is that different officers are assigned to different areas and so since street sweeping is either the first and third or second and fourth week of the month for most residential areas, this will allow different officers to float to the top in different weeks. Having at least a 2 week lookback for the leaderboard is probably best. Otherwise great work!
