Here in Canada, a lot of emphasis is put onto levels. Unfortunately, like in any situation, you sometimes end up with people at those higher levels who are very good on the field, excellent at match management, etc... but just don't know the Laws well at all. You sometimes get lower levels who know the Laws cold, but do not excel at match management, etc.
Is emphasis given to the higher levels? Usually.
Should it be? Usually.
To get to that higher level, you do have to prove yourself to others, and with that comes the experience, the learning of things that are difficult to codify and/or teach (such as match management, reading the game, etc). As such, that experience (like in any other realm) has a large value. As long as the person takes the time to keep up on changes, etc... that person has "proven their worth" so to speak.
But, just because emphasis is given to that... doesn't mean that you shoudn't listen to the lower levels, hear what they have to say, think about the questions they ask. Those questions aren't always as simple as you might think at a glance...
