The addition spectrum of a disordered stadium is studied for up to
120 electrons using the self-consistent Hartree-Fock approximation
for different values of the dimensionless conductance and in the
presence and absence of a neutralizing background. In all cases a
Gaussian distribution of the addition spectrum is reached for 
. An empirical scaling for the distribution width in the
presence of a neutralizing background is tested and seems to describe
rather well its dependence on the dimensionless conductance.
