  We use information from DIS and the two gluon nucleon form factor to estimate
the impact parameter amplitude of hadronic configurations in the dipole model
of DIS. We demonstrate that only a small fraction of the total $\gamma^{\ast}N$
cross section at $x\sim 10^{-4}$ is due to scattering that occurs near the
black body limit. We also make comparisons with other models and we point out
that a quark mass of $\lesssim 100$ MeV leads to a strong variation of the the
$t$-dependence with $Q^{2}$.
