    Personally, I'm also bothered when I hear "5 times more". Is it 6 times as much or 5 times as much?

    The translation from "two times less massive" to "less massive by a factor of two" is pretty straightforward and easily understood...

    The real problem happens in the opposite direction. A star that's 200% as massive as the sun is smaller than one that's 150% more massive than the sun, but many people will give the wrong answer if asked.
