I think you also may have miscalculated. 

Look again, the calculation should be 477 / 75,000 * 100

So that by my linux calculator is 0.636% !!!!

That's .6 of 1%

A very, very low figure indeed.......

So, by my reading, of the 75,000 it's likely that 0.6% used xquery. I think 
that is more reasonable.

Obviously what may have happened is that the statistics passed through the 
"marketing" department for a little "airbrushing" on their way out.... 

They misread .6% and revised it to 7% then upwards of 70%... finally the 
figure they needed for the printing.... the letter spacing finally fitted....

Maybe these are the lost workers from that big auditing company that ran into 
problems lately......
