Personally I think that the current training pipelines spend enormous efforts trying to make it look like they treat people as individuals and not numbers.
Meticulous inspection of reports to make sure that the paper trail is perfect so nobody can complain about anything.
Everything has to be Objective and data based to make the process look scientific despite the fact that if you let even a postgrad scientist look at the numbers they would point out that there are far too many independent variables involved for the numbers to be valid, and you would be better off admitting that the process is still as subjective as it ever was and let the experienced instructors get on with weeding out the unsuitable without having to couch it in faked up numbers terms.
How do you put numbers on "he's a tw@t I wouldn't like on my sqn"?
