My concerns are the parameters mentioned in the draft, and the questions of
any reader or implementor are 1) what will be my start values for these
parameter. 2) Is there any recommendations from the authors or the group?

There was one test for the MPL and I would like to know what was their
parameters' values if possible, however, if not giving by the draft
any example or default for parameters, should that mean that it does not
matter any value will work.
