The spin-flip dynamics of the SK-model is studied numerically with systems of up to 105 spins. For sequential dynamics at T=0 we find a remanent magnetization of $0.085\pm 0.005$ which is about half the value found earlier for much smaller systems. Furthermore we have calculated the percentage of spins which flip n times during the descent into a metastable state. Remarkably, the number of spins which never flip ( n=0) is asymptotically equal to the number of spins which flip only once (n=1). Therefore the dominant contribution to the remanent magnetization comes from the spins which flip twice (n=2). We have found the convergence time, with the system sizes used here, to diverge faster than a simple power law.
