Section 5 says:
Translating this to the packet-based congestion control of CCID 3, the initial CCID 3 sending rate is allowed to be at least two packets per RTT, and at most four packets per RTT, depending on the packet size. The initial rate is only allowed to be three or four packets per RTT when, in terms of segment size, that translates to at most 4380 bytes per RTT.
It should say:
Therefore, in contrast to [RFC3448], the initial CCID 3 sending rate is allowed to be at least two packets per RTT, and at most four packets per RTT, depending on the packet size. The initial rate is only allowed to be three or four packets per RTT when, in terms of segment size, that translates to at most 4380 bytes per RTT. This might be implemented, for example, by setting the initial sending rate to min(4*s, max(2*s, 4380 bytes)), where "s" as usual is the packet size in bytes.
Notes:
Clarification of initial sending rates.
