I highly recommend weekly normalization (average or median) because people usually don't use Maps on Sunday, it seems, so data is all jagged.
I'm happy that I could see, from this data, that weekly usage is increasing slowly but steadily in the last 30 days where I live (which would imply the gears are starting to turn again) and forecasting predicts that in another 7 weeks usage will be back to normal, but I think it's still early get good predictions.
