Outside of the 24 hour window from the flight, it's usually at the 24, 48, 72, 96 hour mark plus or minus an hour or two. Sometimes I've seen it outside these parameters but, hey, it's SHARES so anything an happen.

This has been my general experience. The sweeps generally run very close to T-96, T-72, and T-48; T-24 can be a little looser, with that sweep often running a few hours earlier.
Note also that the e-mail notification can come several hours after the upgrade has occurred. I like to check my reservation at the sweep times so I can grab a good seat before the e-mails go out.
