What do these columns denote? "Amount" & "CalculationAmount" in "Calculations" denote?

Hi! I need help figuring out what the following terms denote:

columns"Amount" and “CalculationAmount” in “Calculations” table
column “Amount” in “Payments” table

Does the Amount column in Payments tab refer to the actual payment that was taken against a particular ticket?

What about “Amount” and “CalculationAmount” in the calculations table?
Am i correct in inferring that the amount refers to the percentage amount that is applied to a particular ticket and the calculation amount refers to the amount that is discounted in absolute terms?

Please direct me if there’s a guide for these terms.

Yes this is correct.
