Re: Is 70ms 14 or 12% faster than 80ms ?

> “X% times faster” is awfully close to the mis-use of that horrible phrase “rate of speed”, which is erroneously used (particularly by law enforcement in the US for some reason) as a more refined way to say “speed” when in fact it means acceleration (“speed” being “rate of change of position” and “rate of speed” thus either being tautology or “rate of rate of change of position”).

45% got it right (37 votes)
37% got it wrong (31 votes)
18% just gives up (15 votes)
