 Initial packets and Handshake packets may never be acknowledged, but they are
 removed from bytes in flight when the Initial and Handshake keys are discarded.
+### Speeding Up Handshake Completion
+When a server receives an Initial packet containing duplicate CRYPTO data,
+it can assume the client did not receive all of the server's CRYPTO data sent
+in Initial packets, or the client's estimated RTT is too small. When a
+client receives Handshake or 1-RTT packets prior to obtaining Handshake keys,
+it may assume some or all of the server's Initial packets were lost.

Wait, do you mean "receives and successfully decrypts Handshake or 1-RTT", or I just get something that is marked as such?
