Note:  Excess values and what they mean are below:

Y
Subtract minimum amount as excess. The line is calculated using the following formula so that the difference between the amount pulled into the table and the Minimum is part of the calculation:
  Result = flat amount + [(amount - minimum) * % rate] 

N
Do not subtract minimum amount. The formula is the following:
  Result = flat amount + [amount * % rate] 
Difference between the minimum and the amount is ignored.
