Short interest is every broker's short position at the settlement date, reported to FINRA and published about a week and a half later; it does not say who is short. Days to cover is the short position over the average day's trading, and the share of the company is against the shares outstanding on its latest filing. A fail to deliver is the balance of shares sold and not delivered by settlement, from the SEC: it can be a short seller who never borrowed the stock, but is as often a late delivery that clears within days.
