"99" means there are 99 shares short - period. It does not mean there are 99 short for every long. Look at "days to cover" which is based on shares short and average daily volume. Even days to cover is somewhat misleading. Apparently if there were 1 single share short, it would report that it takes 1 day to cover the position.
Do this: Click on the "Short Interest" column to sort the list by short interest and look at the row at the top. April 15, 2009 there were 1,835,139 shares short, avg daily vol of 1,257,345, and the amount of days to cover is 1.46.
