Yes, the winner of a race can reduce the congestion window or maybe prevent it from being reduced. |
As I see this: QUIC receivers ignore the ECN codepoint field received in IP packets that carry duplicate QUIC packets (see {{ecn}}). |

@gorryfair made a good suggestion in #2163, which I have taken and tweaked further. It is not sufficient to discard ECN if one QUIC packet is discared, you need to discard ALL QUIC packets in the IP packet.
So @ekr is this resolved or do you expect more than what Martin wrote? |
I think that I can make that call now. If there is a problem, we can open an issue. |

S 21.7
This could use more elaboration. As written, it seems like if you win the race (which you might like half the time) then you will succeed in the attack. Is that true?
