A word to the wise as well:

I've found it easy to end up thinking I'm uploading the changed feed to google when in fact, it's the wrong feed, the cron job didn't run when I thought, I interrupted the export, didn't realize or forgot the feed name had changed between google feeder versions etc.

So when in doubt, also check the feed file date in ftp to see if it's the feed you think you exported. Then make sure that's the one uploading to Google.
This is some excellent information and may explain why several people haven't been able to solve the availability attribute problem in spite of having the correct settings.
