Timewarrior's built-in month report

The best way to learn a tool is to use it a little every day. I tried that strategy with Timewarrior recently (Taskwarrior’s time tracking companion), and within a week I was tracking what I did 24 hours of the day. Not sure if anyone’s used it like this, but the frictionless interface makes it irresistible:

timew start cooking timew stop && timew start eating timew stop && timew start reading timew stop && timew start sleeping

I’m looking forward to exporting this data and getting insights into how much time I spend on different activities per week. Are there positive/negative correlations between time spent on different activities? How many taskwarrior tasks do I get done on average during one of my (perhaps oddly named) “homework” sessions? There’s a lot of interesting data to combobulate.
