Oh how I hate that weasel phrase. You can have a product which is 10x worse in every way but one, and if it's 30% better in that sole exception, you can advertise your worse product as being "up to" 30% better.
Any number after the phrase "up to" tells you nothing about overall performance. It's an empty phrase invented by marketers to exaggerate things while being subtle enough that you might not realize it's being exaggerated. I'm naturally suspicious any time it's used. If you want to impress me, (truthfully) use the phrase "at least x% better."
