It helps you to find the correct sizes of tires in upsizing/downsizing etc plus the difference in speedo readings.

It's not so bad lah..

Maximum Out by 10+/-km/h only.

That is a big difference! it should vary by a few Km not by double digits. Imagine the speed limit is 90Km/h and you are traveling at 100Km/h, which infact is 110km/h..next you will see flashes from the speed camera.
