Feedburner Stat Trouble?

For the last month or so, my Feed subscriber count has been fluctuating wildly - it currently says 1,319 which is correct but (more often than not) keeps showing at around the 900 mark, which is way off the real total. I eventually worked out that this is because Feeburner is having issues with anyone subscribed to the site via Netvibes as they upgrade to their new release.

Whoops.

Apparently they claim subscribers aren't affected, it just makes your stats look more rubbish than they actually are. I've noticed this sudden drop-off affecting quite a few security blogs out there so if you're wondering where all your subscribers are going, it's down to Netvibes. No ETA on when this will be fixed, which sucks.
