We don't need a new API and more complexity and/or code confusion, just
standardize on the unit values for the existing APIs.
1) SNR in either units of db or units of .1 db (I don't care which, although I
prefer the later).
2) Strength as a percentage.
The approach Devin outlined above has my support.
