Try something like
-43,-37,-31,-31,-26,-26,-16,-21,0,-20.25
for the transfer function. You can also use the --plot option to visualize it.

No, the ratio means that an increase by 1 dB corresponds to an increase by 0.05 dB on the output side.

mcompand is for applying different compression to various frequency bands, which is not what you want to do here.
