Never correct?

Ever see commercials for "save up to 50% or more"? So which is it? Up to 50%? Or more than 50%?

Here's some neat software that takes what you say and types it on the screen for you. The only problem is its self-professed accuracy only goes "up to 99%".

Technically, this means that a word would never be written exactly as you wished. A word might be anywhere from 0% correct to almost all letters correct, but never ALL.

At least, that's what the item description implies. But I'm sure the actual accuracy level is 99% period. Almost all words will be typed as intended. On a good day.
