Not to point out the obvious, but Victor was focussing on the 100% part. Obviously it was a figure of speech, but he has a point. Be 99.99999% sure, but unless you've seen one or have any evidence, you don't call 100% based on statistics, because that is blind faith.
I am pretty sure 100% was also a figure of speech. So.....?
Just clarifying and backing up Victor. Maybe it comes from being a physicist, maybe an NF, but I also had a cringe at the 100% statement, figure of speech or not. I think we're in agreement anyway, going by the second line of your post.
Freude, schöner Götterfunken Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum! Deine Zauber binden wieder Was die Mode streng geteilt; Alle Menschen werden Brüder, Wo dein sanfter Flügel weilt.
