Thanks Ptero. That's what I've read in the FPN thread that @Yazeh linked. However, I can't find the same on the R&K site. I believe the "guarantee" was stated in a .pdf, but even the Wayback Machine doesn't seem to have it.
That said, there are enough witnesses quoting it on FPN, in different languages even, that I'll take it as true that the information came from from R&K at some point. So, I'll assume the answer to my question is YES.
