Section 4.1.2 says:

   each direction of transmission (this is usually desirable).  To
   compensate for the Reflector's larger test packet format, the Sender
   appends at least 27 octets of padding in unauthenticated mode, and at
   least 56 octets in authenticated and encrypted modes.

It should say:

   each direction of transmission (this is usually desirable).  To
   compensate for the Reflector's larger test packet format, the Sender
   appends at least 27 octets of padding in unauthenticated mode, and at
   least 64 octets in authenticated and encrypted modes.

Notes:

In authenticated/encrypted mode, the minimum data segment length of TWAMP-Test and OWAMP-Test packets is 112 octets and 48 octets respectively, so the Sender should append at least 64 octets, instead of 56 octets.
