No, it's most likely 300 good reports.
I don't have the link, and my repot "baseline" is:
You have reported 313 posts with 97% accuracy (293 good, 11 bad, 9 unhandled).

Right okay. That's interesting. Let us know once you get those 7 good reports
If we can get multiple sources to confirm this then I'll edit it into the OP.
