I don't get the scenario. It seems that @goelvidhi is worried about receiving an ACK for a large number of packets. This is not a congestion window problem, because it happens even if the congestion windows size remains constant. The root cause is that the ACK of N packets now reduces the number of packet in flow by N. So this is strictly about pacing, not about congestion control.
