(beware, mini-rant)
Yet another thing that somehow people manage to constantly bungle up in the English language is the use of the phrase "X times more". If you're someone who does this, stop! There is an inherent difference between the following:
This is three times faster.
This is three times as fast.
If newspeed = speed * 3, the speed has increased to 300% of its old value, which is a 200% increase (300% = 100% + 200%). This makes the speed three times as much (by definition), which is two times greater: newspeed = 3 * speed = 1 * speed + 2 * speed.

The rule of thumb is:

If xn is t times the old value xo, it is (100 * t)% as much and t times as great, but it is (100 * (t - 1))% greater and t times greater.
What's even more annoying is when people use something like "three times less" to describe "one-third."

Quit it. Quit it NOW.

Here's a quick math lesson to demonstrate why this is completely wrong:

Let's take a value, and call it "x".
Now three times x, would, of course, be 3*x.
So if something is "three times less" than x, then it is x-(3*x) which is -2x.
And (unless x is 0) -2x does not equal x/3.

If you mean "one-third", say "one-third", or at least "two-thirds less" (or fewer, but that's another node).
