- If some job takes me 100 seconds and you can do it in 25 seconds:
- I am 300% slower then you are. (100-25)/25*100
- You are 75% faster than I am(not 300) (100-25)/100*100
- Your performance is 400% of mine. (1/25)/(1/100)*100
- My performance is 25% of yours. (1/100)/(1/25)*100
-
- And yes, to do the job 75% faster (in 75% less time) you need to increase
- your performance by 300%. Vote is not required here.
-
- Surely 75% faster means at 75/100 == 3/4 of the speed, ie 4/3 ~= 133% of the
- time, ie *slower*?
