The Analysis
I don't get what the fuss is that you are making.
Percy's analysis makes it clear that there is room for the balls to be measured as underinflated even if there was no tampering. So far no one has shown that it can't be the case.
Until this is cleared up the punishment is unfair.

Another Delate-gate ...
... with a much more rational outcome.
Lewis Hamilton keeps Italian GP win after stewards' investigation - BBC Sport
Mercedes were investigated on the grounds the tyres were below the minimum permitted pressure.
But the stewards allowed Hamilton to keep his victory after ruling Mercedes had followed safe operating procedures.
...
in case of a penalty for the tyre pressure, which was 0.3psi lower than the minimum amount specified by Pirelli on safety grounds.
...
But the stewards ruled that the tyres were at the correct temperature when fitted to the car and that the blankets which keep them warm were unplugged and at a lower temperature than the maximum permitted.
...
This lower temperature would mean the tyre lost pressure and would explain why it dipped below the minimum, which is why Mercedes were cleared of wrongdoing.
Note: they actually understand a bit of physics and they measure so .3 psi is an issue.

Blankets
does it mean that the track officials are responsible for plugging in the blankets ?
No, I don't think so. It just means that the car had time to cool before the measurement was taken. I don't know what the measurement procedures are or when they are done.
The driver is weighed in immediately after the race. The car is too at some point.
The issue arose late in the race so I suspect that the tire pressures are measured before the race starts or they rely on telemetry (though that couldn't work during the race since the tires heat and cool drastically between corners and straights).
What I am astonished by is that they pull 4 to 4.5 gs on the corners and on one corner at Monza 5.8 gs of deceleration! This is with the slower cars they are running now.
