Earlier quoted context omitted.
The quality gradients are actually tied to number of revisions/number of people who proofread the text. We'll put up more information about the way we proofread and how they relate to the different options for quality.
I would word it differently then. Using the term quality in a sliding scale manner leaves doubt in my mind. I want to know all your work is excellent.
I am replying so that textlaundry know that not everyone is like parent: i.e., I am fine with "Pick a quality: good, better, best" (or "Pick a quality: good, great, excellent"). In fact, I do not like it when vendors pretend that everything they offer, even the cheap stuff, is the best that it can possibly be. I tend to conclude that the vendors\ is either deluded or insincere.
But yeah, if textlaundry can convey in that row of radio buttons (terminology?) that "great" service means that the text is worked on by more editors than work on text using the "good" service, that would be an improvement.
