Now what qualifies as landing?

Collect a large number of pilots, divide them into two pools based upon their performance (low and high). Which pool do you think will incur more expenses to the airline? Keep in mind that some of those costs range from reducing consumer confidence (poor landings or damaged cargo), to planes requiring more maintenance (increased costs of maintenance, planes taken out of service more often), to planes being put out of commission (regardless of whether everyone walks away or not).

A lot of people seem to be measuring value in landings per day, widgets per minute, lines of code per week without acknowledging that the quality of work does have an impact.

There's only acceptable piloting and not. There's no pilot that makes the airline 10x more per flight.
