The fastest grinding method

[Memesbro]

I think you know what this is, but I am theorizing a better grinding method as opposed to the Ford GT Spec II Race Car on Indianapolis in the American Championship

Basically, if you have the DLCs X2011 or you got the X2010, you can drive around Indianapolis in Like the Wind. Here is the math:

I am assuming you want to save up credits for one of the 20 million credit cars, the Chapparals, or the Formula GT. If so, then the Used Car Dealership refreshes its roster at a rate of 6 cars a day. There are 30 cars in the UCD, so therefore it completely refreshes its roster in 5 in-game days. So, you would have to check the UCD every 5 days. Therefore, in my calculations, I will be referring to 5-day blocks between checking the UCD as stints.
The stint would end when you enter the race after looking at the UCD, starting the next stint.

The American Championship gives 97600 credits per race in prize money
Like the Wind gives 70000 credits per race in prize money.

The shortest races by far in both events is doing 5 laps around Indianapolis (Second race in Like the Wind, first race in American Championship)

With the Ford GT Spec II, I can consistently finish the race around the 3:45 (or 225 seconds) mark
With the Red Bull, I can get 2:45 (or 165 seconds), and that was with the AI blocking me, making me lose around 2 seconds. And I didn't tune it that too much, so the limit could be closer to 2:40. I will use 2:41 as the benchmark.
So, the Red Bull can go over a minute faster than the Ford GT, big deal. But this is important

Loading times are hard to account for, since you could either have the game installed on your PS3, or run the game on emulator, or not have it installed and just have it on the disc. They should be similar for both since both races are technically the same, just different cars racing. So we can ignore them.
Menuing is also hard to account for, but an estimation, without load times, would be around 6 second between races, and 15 seconds when checking the UCD. With load times, it would probably be 2.5x longer with the latter, which is a fair estimate.

I will be using BEDMAS for the following equations, meaning I solve the brackets first, then do the adding.

For the Red Bull method, you would be grinding for around:
(161x5) + (6x5) + 15 = 850 seconds, or 14:10 per stint
Alternitvely, if you don't want to check the UCD, just subtract the 15 seconds for checking the UCD

For the Ford GT method, you would be grinding for around:
(225x5) + (6x5) + 15 = 1170 seconds, or 19:30 per stint (over 5 minutes slower than the Red Bull method)

To find which one is better, we should divide the amount of credits per stint by the length of the stint in minutes, giving a credit/minute rate.

• The Red Bull method earns 350,000 every 14.1 minutes
• The Ford GT method earns 488,000 every 19.5 minutes

Doing the math, we find that:

• The Red Bull method earns 24,822 credits per minute (rounded to 0 decimal places)
• The Ford GT method earns 25,025 credits per minute

So therefore, no. The Red Bull method is not better than the existing Ford GT method, but considering how similar the numbers (only 203 credits difference in the credit/min rates), I can suggest using it if you are in a rush and want to get through the UCD faster.

And for those wondering about the no spending challenge I am doing, don't worry, I am still doing it. I have even planned a theoretical route that could either make the challenge possible or impossible

I think Dream Car Championship skipping Nürburgring is the best credits per hour.

I think Dream Car Championship skipping Nürburgring is the best credits per hour.

If the Monza and Le Mans races were in the dry then it may have a shot

The X2011 can do the Indy race 5 laps in 2:40, so it would be reasonable to double that and get 5:20
The X2011 can do Monza around the 1:00 mark per lap, and since it is 10 laps, we can reasonably deduce it can be done around the 10 minute mark in the dry
Tokyo R246 can be done around the 1:00 mark per lap as well, and at 10 laps, this is another 10 minutes
Le Mans in the X2011 can be done around 2:25 per lap, so over 3 laps this would be 7:15 on dry conditions
And skipping the Nurburgring would take around 7 seconds.

So that is 5:20 + 10:00 + 10:00 + 7:15 + 0:07 = 32:42 excluding loading times.
And since each race gives 86,600 individually, that is 433,000 per 32:42 of racing. But you can double that because it is a championship. So it is actually 866,000 per 32:42

32:42 is 1962 seconds, so dividing 866,000 by 1962 is 441.38... per second
Multiply that by 60, and you get 26,483 a minute.

But championships take longer to load between races than single races, so instead of the 6 seconds per single race, it is around 20 seconds per race in a championship, approximately. And to finish the championship and check the UCD, add another 5 seconds to the 15.

So 5 races, that is 80 seconds, and add the extra 5 seconds at the end, that is 85 seconds, which is an addition of 54 seconds.

Adding 54 to the previous 1962 seconds we get 2016 seconds.
And with that, the credits per second plummets to 429.56...
Multiplying the result by 60 gives a new number of 25,773.8 (25,774 for simplicity sake) per minute, which is a massive drop from 26,483, but still is way higher than the 25,025 per minute with the Ford GT method

So yes, you are correct. That is the best credits per hour, even accounting for loading times and the longer transitions.

I can't remember where to find it, but there is an excel file called GT5 matrix that has all this information. All the races, all the cars.
