  We present an extended Bayesian analysis using Trajectum where the initial
condition can now include binary scaling. For the far-from-equilibrium
evolution before hydrodynamics we introduce an interpolation between free
streaming and a holographically inspired evolution that exhibits fast
hydrodynamization. We find strong evidence that binary scaling is incompatible
with experimental data and find evidence that the holographic
far-from-equilibrium evolution is preferred. We end with a discussion on
several changes and improvements in the Bayesian framework.
