[polyphenol]

BAM! They got you.

You (like any reasonable person) concluded that it meant one fifth of the scrubbing, right?

What the ad people really meant was that you should say "less scrubbing" five times: "Less scrubbing, less scrubbing, less scrubbing, less scrubbing, less scrubbing" It's a lovely mantra, but not quantifiable. It could mean 80% less scrubbing or it could mean 0.0001 less scrubbing. Neither outcome would be deemed a lie if it wound up in court.

You are likely right - but if I don't believe either version, it doesn't result in a sale to me!

Linguistically I stand by my point. "times" and "less" cause a horrible clash.
