How are Excitement, Intensity and Nausia ratings calculated exactly?

[Typhoon]

Having recently seen the RCT Wikia, I'm beginning to understand just what goes into determining these variables but I was wondering... Would be possible to take a look at the equations (if any) behind the three ratings?

Thanks.

Can anyone translate this into something a simpleton like me can understand?

In short, it grabs and executes the function that calculates the actual data, which is different for each ride type. To give you an idea of how many different functions there are with each having different calculations, check this list: https://github.com/OpenRCT2/OpenRCT2/blob/develop/src/ride/ride_ratings.c#L4140

Thanks guys! There seems like a lot of ride specific constants for many individual things. I kind of want to try tabulating them if it hasn't been done already but I'm not sure what to look for. From https://github.com/OpenRCT2/OpenRCT2/blob/develop/src/ride/ride_ratings.c#L4140 correct me if I'm wrong but just as an example, from lines 1405 to 1437, the numbers between them all apply to a spiral roller coaster?
