I'm currently getting really irritated by an advert on my phone which states I could increase my battery life "up to 200% or more!"
Well, which is it? Is it up to 200%? Or is it more? It cannot be both!
Also, why say 200%? This is a personal gripe of mine where people (that evil, irish, pop neanderthal that is Mr Walsh as an example) constantly say "you gave that 110% tonight!" to contestants on shows or to sports people. You have to give a point of comparison, and it is the same with these flamin' stupid adverts about battery life. The fine print you see on the screen which gives you a comparison, where it is shown, is gone too quickly to make sense of it.
As my wife just said, you never walk in to a shop and ask for "125%" of that cake..
The cake could be 100% of one cake + 25% of another cake, making a larger cake - that is 100%.
