Seems like a lot of discrepancy in the incomeAmt based on what I'm reading here. Mine would be 50% too high.
Perhaps incomeAmt is the income you provide to delta? If so, multiply the number by $100 and it sounds pretty close to what I spent on Delta in the past year.
discSpendingAmt in my case is exactly the same as what I spent on my DL Amex last year.
