Jaguar fart car question

I’m looking at a couple of F-Type demo/loaner/fart cars. I saw a top on here stating that from 3000-9000 miles there is a .20/mile adjustment to the residual. Does that get larger after 9000? Also, how many miles can be on the vehicle to still qualify for any incentives or dealer cash? I know for BMW it has to be under 5000, but I’m not familiar with Jaguar. Thanks.
