Ok I shouldn't say it's zero, but negligible, not much higher than zero. I especially objected to you using 20%, etc. You're talking a fraction of a percent, so it's actually not all that useful to talk about. Nice try though.
I should have really trimmed out that quote chain...
I'm not claiming 20% is a potential attack, that was someone else. I just wanted to provide a USEFUL response to your statement instead of the X-Files face palm someone else gave.
