The faster you are through those speed check points the more bonus you get...
Value???
Dont know since i am too busy avoiding swerving Bob, avoiding the invisible wall, and trying to catch as much air as possible in the mist of all that...
The jump bonus also begs the questions:
How far do you have to jump or how high do you have to be to get those jump bonus....
Guys, lets get thise protractors out...
The only thing you need to know really is: clean speed.... thats the whole intention of this rally
You gotta be fast overall
Fast passing the Bobs
Fast catching air
Faster throught the speed radars
And avoid going off road...
Edit: sorry i cant help you if you were expecting any specific numerical values... maybe someone else can tell us
