[opus] Opus (or Silk) and E-Model

I'd like to calculate the MOS score (or R-factor) using the ITU-T
E-Model (see https://www.itu.int/ITU-T/studygroups/com12/emodelv1/tut.htm)
for Opus and/or Silk codecs:
- Opus NB, MB, WD, and SWB
- SILK NB, MB, WD, and SWB
However, some of the required parameters are missing, in particular:
- Bpl: packet loss robustness factor and
- Ie-eff: equipment impairment factor
Does someone knows those parameters or where could I find them?
Alternatively, I think could derive those numbers from the R-Factor
equation if I could simply have the theoretical max MOS.
