Doing the tests with a cold engine will not prove a thing - an engine @ normal operating temps will always give the most accurate results.
After saying that, at 92,000 miles I think the results are not perfect but not too far off the optimum......
Theres a lot of owners out there would love those leak down resulta at that mileage.
