> +short packet header, the number of significant bits are encoded in the most
+significant two bits of the first octet of the encoded packet number:

+| First octet pattern | Encoded Length | Bits Present |
+|:--------------------|:---------------|:-------------|
+| 0b0xxxxxxx          | 1 octet        | 7            |

+
+Note that these encodings are similar to those in {{integer-encoding}}, but
+use different values.
+
+The encoded packet number is protected as described in Section 5.6 {{QUIC-TLS}}.
+Protection of the packet number is removed prior to recovering the full packet
+number.The full packet number is reconstructed at the receiver based on the
+value of the most significant two bits in the first octet (to determine the

yep, this is better.
