Asphalt 8: Airborne/Upgrade Rank Percentages

How to obtain upgrade rank percentages:
 * Acceleration = Total amount of rank points gained by maxing out acceleration divided by the total amount of rank points gained by maxing out all aspects
 * Top speed = Total amount of rank points gained by maxing out top speed divided by the total amount of rank points gained by maxing out all aspects
 * Handling = Total amount of rank points gained by maxing out handling divided by the total amount of rank points gained by maxing out all aspects
 * Nitro = Total amount of rank points gained by maxing out nitro divided by the total amount of rank points gained by maxing out all aspects

For example, let's take the Mercedes-AMG C 63 Coupe Touring Car 2014. Maxing out its acceleration adds 28 rank points, maxing out its top speed adds 112 rank points, maxing out its handling adds 28 rank points, and maxing out its nitro adds 112 rank points, for a total of 280 rank points. How much does each aspect make up the total amount of rank points that can be gained by maxing out the car? In this case:
 * Acceleration = 28 / 280 = 10%
 * Top speed = 112 / 280 = 40%
 * Handling = 28 / 280 = 10%
 * Nitro = 112 / 280 = 40%
