  Let G be a second-countable locally-compact Hausdorff groupoid with a Haar
system, and let {x_n} be a sequence in the unit space of G. We show that the
notions of strength of convergence of {x_n} in the orbit space and
measure-theoretic accumulation along the orbits are equivalent ways of
realising multiplicity numbers associated to a sequence of induced
representation of the groupoid C*-algebra.
