Yet again, you fail to understand that not everyone does things the way you do. No common sense has been replaced here. Online calculators are not the work of the devil. They just make it a bit easier to optimise your tyre pressures if you can be bothered.
The OP asked for advice about optimal tyre pressures. Someone pointed to a well-known online pressure calculator and then you and a few others have to troll it as a dumb idea, just because you do things the old way as if that's the holy grail.
