if Nissan says 35% degradation is acceptable by the end of my warranty
Lucky for you, your use case did not depend on your understanding of the warranty. It behooves you to step off your soapbox, at least until you grasp the facts.
FYI: your warranty states that for the first 5 years/60k miles (whichever comes first, that degradation less than ~ 33% from day #1 of ownership is not covered and past that period any amount of degradation is not covered.
Tangent: I for one would be much happier with a pro-rated warranty.
