Well.. i can easy tell you why your time is slow.. most people that do 100-200 time start usually at 50kmh and slap them self through 100kmh mark when the counter starts.. that will shave off a sec, maby even 2.. for you to START from 100 takes you alot of time to build up speed.. ALL THO i personally think this is the correct thing to do.. that means start from 100..
