Is 70ms 14 or 12% faster than 80ms ?
Reading many stackoverflow response, I am still confused.
Most answers claimed (1 - 70/80), or 12.5% faster
If the math is right, it is impossible to be 100% faster.
10 times faster (1000%) is meaningless (time is negative)
I normally avoid using "percentage faster", and prefer ratio:
Speed at 80/70 = 1.14X
