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
