Outsider perspective: you have nailed the training pathway, at least conceptually. Many level five practitioners are so far out of touch with level one that they have a tough time getting anyone else to level three. Keep up your good work!

I've commonly run into this, myself. By the time someone gets to level four or five, they tend to associate more with people of their own level and it has been so long since they were themselves a junior that it becomes hard for them to relate. They expect competence and familiarity with the process from their colleagues, even if said colleague is a fresh new hire.
It can be pretty tough to overcome, from both sides.
