Query: Strong stationary times for features of random walks   In [4], we examined the use of coupling to obtain bounds on the mixing time
of statistics on Markov chains. In the present paper, we consider the same
general problem, but using strong stationary times rather than coupling. We
discuss various types of behaviour that may occur when this is attempted, and
analyse a variety of examples.
