I think you're probably right....and its conceivable that the number short when the news came out on September 30th, it could have been higher than the 700K short for trades settled up to Sept 30th.  

What we know right now is that as of October 11th, give or take, that the number borrowed and dumped back into the market was 416,827.....and now volumes are grinding back to less than even anemic levels again.  AHA can't get  here soon enough....I suspect there won't be anything too significant announced at the AGM.
