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...... -- Computergrid : The ones with the most connections win.
