-
- Not exactly. 400% is a nonsensical term. Percent (%) means 'per hundred' or
- 'of each hundred', and thus is only meaningful for values between 0 and
- 100 (inclusive). Percent is best used for absolute measurements, rather
- than relative comparisons such as the above example.
-
- The use of percent in relative comparisons naturally leads to subtle
- misunderstandings. Thus its best to say something like "machine A
- (at 20 M op/sec) is four times as fast as machine B (at 5 M op/sec)."
