so with my summary, I guess I have one question.
Suppose you own a mk1 unit and an mk2 unit.
If you make a 2.0 profile on your mk2 unit and load it on you mk1 unit, it will be played at a lower resolution.
How would this lower resolution version compare to you creating the same profile on your mk1 unit, using the 1.0 method of making profiles? In other words, will a lower resolution 2.0 sound and feel different than if you just made that profile using the 1.0 method?
At the very least, a 2.0 profile might be more accurate due to not having the 'refining' step.
