Here are the values I know:
A = 200
B = 1.75
C = 0
A2 = 1.8
B2 = 0.93
C2 = -0.64
T = 14
It is possible that some of these values are not used. The other formula (which was much easier) was simply called "exponential" and consisted of:
A = 240
B = 1.5
And the formula
Y = AB^X
This one consists of quite a few more variables and my googling for "exponential_flat" and variations of it were fruitless.
Here are some of the output values for values of X. These should be all correct but there is a possibility that some of them are off by a little.
1 - 448
2 - 717
3 - 1,147
4 - 1,853
5 - 2,936
6 - 4,698
7 - 7.516
8 - 12,026
9 - 19,241
10 - 30,786
11 - 49,258
The reason that some of the values may be off in this set is because the data was crowdsourced and I cannot confirm the numbers. Let me know if you have any more questions and I will answer them to the best of my ability. Thank you for any help you may be able to provide.
