> It’s fairly easy you calculate the MTTF when you design anything.

Where did I disagree with this?

What I'm saying is that MTTF is measured in usage time, whereas warranties are measured in calendar time.

The range of "normal" is massive for things like cars and laptops.

Again, provide a source please. Otherwise this is just unprovable speculation on your part for something that is theoretically difficult in the first place.
