Yeah, but if it measures every 1 gram at 0.98 gram, it will display less in the end

This might be compatible. As the pass band should be wide enough to be in the same range stil.

Yeah, you “set” it when you filled it. Then it knows the rotations to look for. And if it is off by a lot, it warns you.

Yeah, but this is the system based on the rotations per meters. Which sucks as it’s not that accurate and only warns you when it’s already very low on air pressure.

The accurate one’s are veeeery expensive.

The new ones are actually reaaaaly fast with booting

Well,

1 Olympic Swimming pool = 50m * 25m according to wikipedia.

That means: 1250m2 per pool. Now multiply this by 1140: 1.425.000m2. Which is 1.425 km2

Yeah, but for short trips this doesn’t apply. E.g. I might drive 30 minutes for a 10 minute stay/task.
