I think you belong to a small percentage of the population doing that. Most people don't bother with such detailed life microoptimizations.

I think people do, but it's subconsciously.

Things are constantly changing. For example, a new building might have two or three tenants, so entire floors can be skipped. But then five years later, the whole building is full. I would bet that every new algorithm after LOOK is just differentiation in a competitive market.
