These are all non standard immature personal procedures. No company asks you to do it. These come out of boredom of the routine so you try to become creative and as a bit of show off.Cockpit is a dangerous place to be creative. If not stopped in its track leads to inflight deviations and incidents. I had a collegue who would never use Auto Brake and full reverse on 747 till one day landing on a shorter RW in heavy rain trying to do the same thing went off at the other end. Aircraft and pilot both were on ground for months.
