LOL, Tom. Didn't mean to insult your intelligence--I hadn't read the brochure and obviously thought your question was based on your own confusion.
Apparently many others found the dilution ratios confusing (along with the brochure's writers), because the current machines just direct the user to use a capful for so much water (I forget how much). It seems, though, that older generations were better at mental math overall due to the absence of calculators.
Ah, yes, Mrs. Bucket (Bouquet)! She would undoubtedly have all the answers!
