It's too bad that they say it will take up to 30 days to process the request. You can get the US data online right away.
I just got the results from my privacy act request, and it shows all of my entries and exits within the timeframes they said they collected data on, and had both my Canadian and UK passport info, so they do link the entry and exit records even if you use a different passport.
