2020 Mazda CX30 Premium Lease Eval

Located in Buffalo, NY this is the dealer that has given the most discount so far please evaluate. Dealer told me this is the absolute lowest discount he will give which is more than the 5 other dealers that actually replied to my email are giving me.
Lease Term: 36/12
MSRP: $30,990
Sale Price: $28,950
Lease rebate: $360
Loyalty Rebate: $750
Money Factor: 0.00071
Residual %: 60%
Residual: $18,594
Tax Rate 8.75%
Acquisition, NYS DMV Fees DAS: $1038.97
Monthly Payment $324

Here is the calculator, which is slightly off and I cannot figure out why. Mazda is waiving first month payment this month as well. I know the discount is only 6.6% I countered one last time with $28,450 and he would not budge. RV is correct and MF is base rate. Any advice at all would be great.

Comprare it to the deal being offered by @AutoNinjas
