We discuss the dynamic critical behaviour of a Monte Carlo algorithm for self-avoiding walks of variable length and free endpoints. The algorithm works in the unorthodox ensemble consisting of all pairs of SAWs such that the total number of steps Ntot in the two walks is fixed. In two dimensions the autocorrelation time in CPU units grows as N≈1.5, and the behaviour improves in higher dimensions.
