Anders,
I do not work with a deflection micrometer so I can only guess.
But it looks like
1. The thing with left and right ski is probably just a guide not to be
too concerned about. There is no left and right ski in today's world.

2. of course he will have a short grip zone for klisters. No rocket
science there either.
One applies Klister wax just under the foot. (heel to toe) no more or
the ski will have no glide.

3. the numbers. 0mm = 100% of bodyweight on ski closed
1.5mm = ? 80% of body weight on uphills
2.0mm = ? 70% of body weight grip when he is
tiered
ask him about the numbers I have no clue
