Missing text - Reliable data transfer on top of an imperfect link #98

I believe there is some text missing in "Connecting two hosts - The datalink layer - Reliable data transfer on top of an imperfect link".

Right after the "Checksum - CRC note", the next paragraph starts with "Unfortunately, retransmission timers alone are not sufficient to recover from segment losses. ". However the text doesn't talk about "retransmission timers" before that point.
