This paper demonstrates the occurrence of the feature called BRAVO (balancing reduces asymptotic variance of output) for the departure process of a finite-buffer Markovian many-server system in the QED (quality and efficiency-driven) heavy-traffic regime. The results are based on evaluating the limit of an equation for the asymptotic variance of death counts in finite birth-death processes. Keywords: Queueing system critical point stochastic process limit Poisson distribution asymptotics stationary Poisson queue asymptotics Halfin-Whitt regime queueing output variance asymptotics birth-death asymptotic variance
