Wait a minute. It's not sufficient to say that the (distribution of the) angle of reflection is not a function of the angle of incidence. If, for example, the angle of reflection were constant 90%, it's pretty clear from the diagram that conditions wouldn't have changed much, in fact would probably have gotten somewhat worse. For random reflection the situation is murkier, but it's at least plausible that, since the random distribution would have to be centered around 90%, it would behave similarly. Time to run more simulations.
