Yes, we know a Pi 5 must and will tolerate 5.5V but that doesn't make it the recommended maximum VIN.

If regulations require an ICE vehicle to be able to hold 55 litres of fuel, and I can confirm my vehicle can hold 55 litres of fuel; how much fuel can it actually hold, how much fuel can it hold before it starts pouring out the filler pipe, sets off an over-filled alarm, refuses to start because it's over-filled ?
Cannot find any of that data in my car owners manual. Just says 55L.
Mine says 61 litres, but at least on a car you can usally determine the limits by non-destructive testing. That's not so with a Pi 5.

What is the recommended maximum VIN of a Pi 5 via the USB-C connector ?
What is the recommended maximum VIN of a Pi 5 via the power pins of the 40-way header ?
What is the absolute maximum VIN of a Pi 5 via the USB-C connector ?
What is the absolute maximum VIN of a Pi 5 via the power pins of the 40-way header ?
What devices are fitted to provide over-voltage protection and how do they connect to the supply?

The Pi 4 datasheets indicates the absolute maximum VIN is 6V. One mod told me the absolute maximum VIN on a Pi 5 and every other Pi is 5.25V, but that contradicts what the Pi 4 datasheet says, what the USB spec seems to require.
