See this posting and the next seven if you wish to plan the races for A-Spec points. This thread is meant to be used with the thread https://www.gtplanet.net/forum/showthread.php?t=61761 ; 200pt A-spec races.
Since I learned about the A-Spec points in GT4, I was determined to figure the point system out. This work can be used to help determine a car and options to use to obtain 200 points in a race.
This initial work is posted Sunday, 9/25/05. This first posting and the several that follow are my work exclusively with the exception of hints by others as how things work. All calculations and values are my own work. I am like that in recognizing I make my share of mistakes and wish not to copy others mistakes.
I am known as Wild Cobra Z28 in this forum, and other places on the net. I even use Wild Cobra on the megatouch games. I have no problems with this information being used, copied, and widely disseminated. It would be nice to give me credit by name however. I know nothing of copywriting, but this can be classed as public domain as far as I care.
All cars in GT4 have a base value. At this time, I do not have the base value, and it isnt necessary for calculations. I have placed a value on all cars that can be driven for A-Spec points. My values are the cars as-is, unmodified. The exception to this is that I have extrapolated maximum worn values for the cars that cannot be bought used.
I have place a value on the first lineups of each race. Some races use the cars in their stock form and each lineup can be calculated using the opponents cars averaged values. The method for determining the A-Spec points you will get is to take your car value and any power, weight, downforce, and tire multipliers. Subtract this from the line 1 value or calculated values of the cars in the lineup. Add 60 points. First of all note that my method is not perfect and the car and race values may be a point or two off. I have however always been no more than 1 point off from my calculated to actual points of the cars I tested.
The next several posting will be:
1) Car Values in Alphabetical Order
2) Car Values in Order of Value
3) Tire Multipliers
4) Power Multipliers
5) Weight Multipliers
6) Downforce Multipliers
7) Race Values
The multipliers all work together. You can determine very close, the value of modified cars and the points they will get in a race. Simply multiply all changed multipliers together and the cars stock value and subtract it from the race values and add 60 points. Anything less than 10 points or negative will be non linear with a 1 point minimum. Anything above 200 points will be 200 points.
This posting and the following seven will be updated from time to time. I will post in the 200 A-Spec point thread letting people know when I modify any of these 8 posting.
The two car value sections are complete. All cars have been valued. They are slightly different from my postings in the 200 A-Spec point section. I revised the zero crossing. Most values are a few points less. I also corrected almost a dozen car values that were off through a typo. Some values still may be off. I hope my mistakes are to a minimum.
The tire multiplier section is pretty simple. Use the table that reflects the cars stock tire and use the multiplier that reflects the front tires you place on the car. Only 4 of the tables exist at this time. The most common starting tires are S2, S3, R1, and R3 tires. These are the only four tables as of the first draft. Other numbers are easily extrapolated with simple algebra.
Power multipliers are mostly undetermined. I am looking for a formula that is likely logarithmic or exponential to take the stock power and new power for a calculation. I have not done much work yet and so far my work is inconclusive. Power for used or fully work cars is 90.25% and a multiplier of 0.9686.
Weight and downforce multipliers are similar to power multipliers in that I have a long ways to go still. I have determined however that they are a multipliers like the others. These three sections are primarily placeholders at this time.
