 When a PTO timer expires, a sender MUST send at least one ack-eliciting packet
 as a probe, unless there is no data available to send.  An endpoint MAY send up
-to two ack-eliciting packets, to avoid an expensive consecutive PTO expiration
-due to a single packet loss.
+to two full sized datagrams containing ack-eliciting packets, to avoid an
+expensive consecutive PTO expiration due to a single lost datagram.

If you send 1, it might be lost.  Ideally, fewer is better, so the question of 1 or 2 was left to implementers.
