So far the mismatch hasn`t bothered me that much... That sounded like a LOT of work...
Not a lot, but some... If you have an experience with mathematic, that is mapping points from one (arbitrary) curve to another (arbitrary) curve. In that particular case, both curves are exponential functions with different parameters. So, it is not a big problem.
If you do not understand what I am speaking about, just ignore the explanation. Simply define your feeling from it (either now or later, once you have use QU+Sonar combination for a while):
* looks a bit ugly, but not important
* a bit annoying
* periodically makes your mix wrong
* show stopper
and I will put corresponding priority on that change in my TODO list.
