good analysis. worth mentioning that the h2 test actually respects the congestion window.. this helps both at the sending-too-slow stage, and also at the sending-too-fast stage which can easily be shown with h1 using parallel connections for large objects. (the parallelism essentially bypasses the congestion control at startup)
