Gu,

The argument that was in the (now nonexistent) appendix A used no
assumptions about the way information is extracted from losses.  (But
I goofed, and instead of alpha>1, it works for 0<alpha<1.)  The
implicit assumption -- but assumption implicit already in the whole
response function model -- is that there is, indeed, such a thing as
``loss probability'' (this is needed for Shannon's formula to be
applicable).
