I see the stove you refer to on stoves.bioenergylists.org but am
unfamiliar with it, I presume it is sold online?

Traditionally primary air controls power and you note also the moister
the wood the more primary air. So I agree there must be good control
of primary air over a range of feedstock, the exception would be
something guaranteed to be homogeneous, like pellets.

This last bit worries me; to my mind the big reason for using top lit
updraught is that it produces very few particulates, this is because
the offgas is fairly rich and largely devoid of inert dilutants like
CO2, N2 and H2O. If the pot has become sooty this points to the
secondary flame having been quenched before completion. Possibly not a
problem in a camping scenario but just what we want to avoid when
considering indoor air pollution.

It's at a time like this that we appreciate why indoor air pollution
is significant in its effect on the respiratory system.

Take care and keep safe.
