The other area that this issue shed light on is that if there is a
range, the minimum is what will be accomplished by most companies.
It is unlikely that most companies will seek the high end of the
range. On the phone call where this issue was discussed, I believe
there was only one company that exceeded the 12 db range. :)
Best,
Janice
