Hello everyone I was thinking over the years of a mathematical equation that gives accurate results to help deciding which car is the best to choose based on specific classes, so here is my suggestion so far:
  • Each car will be tuned to the finest limits accoarding to specific tracks in a way to evaluate four main factors (top speed, Avg speed, Acceleration and performance points given by PD)
  • the Tracks used are:
    • Special Stage Route X (Fictional) (for top speed mainly and Avg speed_USA) + PP_USA
    • Suzuka Circuit (full Circuit) (for Avg speed_Japan) + PP_Japan
    • 24 Heures du Mans Racing Circuit (full circuit) (for Avg speed_France) + PP_France
    • Nürburgring (24 Layout) (for Avg speed_Germany) + PP_Germany
  • The mathematical formulation will be as following:
    • Evaluation point EP= Top Speed_USA + Avg speed_USA + (Avg speed_ Japan + Avg speed_France + Avg speed_Germany)*(1.2) + Avg PP
    • Avg PP = (PP_USA + PP_Japan + PP_France + PP_Germany)/4
Hint:
  • The mathematical formulation takes into account the following:
    • The average point performance because it will be changed based on each track so in Special Stage Route X the main focus here is the speed not the acceleration, so this means that the changes should be made to the tuning system. However, the average value is taken into account so that it is weighted equally to summation of all Avg speeds because this is the main focus which reflects the overall performance
    • The top speed is also an important factor. However, it will be calculated only once since normally this value is far bigger than any other values regarding Avg speeds so in order to be weighted equally to Avg Speeds, it is calculated only once
    • The tuning system will take into account all factors + soft tyres for maximum performance
    • Each race will be against 19 AI on highest difficulty starting from position 20 (last position) in order to test also the ayrodynamics and slip stream and how each car is capable of surpassing other cars
    • Special Stage Route X (Fictional): 2 laps, Suzuka Circuit (3 laps), 24 Heures du Mans Racing Circuit (2 laps) + Nürburgring (Nordschleife) (2 laps)
    • The equation is elaborated and modified to close the gap between the sum of top speed and Avg speed USA from one hand and the sum of all Avg speeds when testing on Suzuka Circuit, 24 Heures du Mans Racing Circuit and Nürburgring (24 Layout) from another hand so that the balance is achieved to make sure that no faster worse performance cars can beat slower better performance cars that easily
    • I am open for any suggestion regarding changing the formula or adding other factos into it
    • Please if you are interested in this project tell me your cars list to be evaluated first

Why don't you post them all in this thread?

Because it is a very very long journey and all cars will be tested so I though that it is better to discuss each car separately because also if I find better settings I will re-test again especially when new updates come, so for new comers or others they will find this post so long to check which page if we have at least 429 pages, that is why I decided to separate the tests until we have the final results for each class

How is that newcomer supposed to find 429 threads? Much better to have your thread with the first post containing links to the post for each car.

try saving this link and just look back at it later on in the week.

not difficult to do,especially if youre really interested in the results
 
Nice work. I think the scoring system might need an overhaul though, because the equation has a strong bias towards high speed tracks. An average speed of 100 km/h on Route X, with a top speed of 120 km/h, is worth more points than an average speed of 200 km/h around Nürburgring, which is quite absurd.

I would suggest that you change the scoring system so that the average speed is compared to the average speed of some baseline car around the same track: score = 100*(average speed)/(baseline average speed). In the figure below I’ve made a comparison between the current system (score 1) and what it would look like with these changes (score 2) :

Notice how in score 1, Route X accounts for nearly half the total score for each car, while in score 2 the distribution is fairly even between all the tracks. In this example I’ve chosen the R33 GT-R to be the baseline car, which is why its score is 100 for each track.

Edit: Another suggestion is to add Tsukuba to the list of test tracks, I think it would be a good balance against Route X.

I really thank you for your suggesstion and it is really interesting. I studied the new model for hours and came up with some points:
  • the average speed is compared to the average speed of some baseline car around the same track: this point is really crucial since the new scoring system depends on it. Based on what I saw from the new scoring system you chose R33 GTR as a baseline since the avg speed is approx 60.98% from the avg speed of Tomahawk which means that you are trying to take always approx half the value as a baseline for each track. However, this approach will be difficult to follow in other tracks such as suzuka since the avg speeds are closely together more than those in USA route x which in turn means that no matter how the car is performing well, the gap (the difference in scoring 2 at Suzuka )between Tomahawk and other cars will be smaller than that in scoring 1 which means it is unfair to the faster car from one hand and the results will not be conclusive for similar performance cars from another hand especially between R33 GTR and F140 FXX. It means that it depends on your skill while driving without making any errors which is practically impossible especially when driving against one make cars during testing on suzuka, so if you re-test both R33 GTR and F140 FXX severals times you will get several results and we will never know which car really is better. This error will be also for other tracks Le Mans and Nürburgring.
  • Equation has a strong bias towards high speed tracks for scoring system 1: the scoring system one calculates 3 mains things top speed only once , avg speed for 4 tracks and average performance points, so lets calculate the weighting system on Tomahawk as a worst case scenario since it has the highest speed on the game:
    • Top speed: 656 which means (656*100)/3492 = 18,786%
    • the total of average speeds since they reflect the overall performance on tracks: (610+248+345+287)*100/3492= 42,669%
    • The average performance point: ((1346+1348+1347+1347)*100/4)/3492=38,547%
  • Results analysis for scoring system 1:
    • as you saw from the weighting system that the top speed has no significant impact on the whole equation since it is only 18,786% from the total score which is 3492
    • the equation says that instead of depending on only performance point given by PD to determine which car is better, it gives only 38,547% from the total score to performance point
    • the total of average speeds are calculated as a single entity all together to contribute 42,669% from total score, that is why I decided to test each car on additional track (4 instead of 3 intially USA, Suzuka, LeMans and Nürburgring) to reduce the effects of top speed and performance point from one hand and to test each car on more diffierent tracks from another hand
    • The scoring system 1 compared to the scoring system 2 increases the gap (the difference in scoring 1 at Suzuka) between cars especially between R33 GTR and F140 FXX in a way that even if you commit some minor mistakes driving against one make AI cars, it still gives you more conclusive results than those in scoring system 2 and this also applies to other tracks as well and also it gives each high performance car the points it deserves since it is no longer centered around weaker performance cars (chosen baseline cars) as well
Hopefully you understand what I meant and of course I really appreciate your contribution and efforts to make the mathematical form more elaborative :) and I am really curious if you bring up more ideas to make the mathematical calculation more accurate
