- He's right, of course. And one might add:
- You take 25% as much time as me. (Or one-quarter)
- You take 75% less time than I do. (Or three-quarters)
- I take 400% as much time as you. (Or four times)
- I take 300% more time than you. (Or three times)
-
- And the one I prefer, at least when the factor involved exceeds about 2:
-
- You are faster than me (or I am slower than you) *by a factor of 4*.
-
- No ambiguity there!
