I think rounding can adequately explain different Fame rewards for the same R$ rewards.

R$ rewards are all in multiples of 40 and Fame are all in multiples of around 70. The fact they are both in multiples of 40 and ~70 seems to indicate to me that both are rounded from a 'behind-the-scene' unadjusted reward value.

Let's assume there is an unadjusted reward value. To get the actual R$ reward: take the unadjusted value and round up to the nearest 40. To get the Fame reward: take the unadjusted value, divide by 5.5 and round up to the nearest 70-ish.

Let's say a race has an unadjusted reward value of 1,970. The actual R$ reward would get rounded up to R$2,000. The Fame reward would be 1,970 / 5.5 = 358.2. Round that up gives 360 Fame. This is the reward we see in Street-Spec Skirmish 6.1.

However, let's say a race has an unadjusted reward value of 1,990. The actual R$ reward would also get rounded up to R$2,000. The Fame would be 1,990 / 5.5 = 361.8. This is more than 360 and would get rounded up to 430, even though the difference between 358.2 and 361.8 is less than 4. This is the reward we see in Pure Stock Challenge 8.1.
