A separate topic brought to light the fact that, with good signals, a surprisingly short transmission (either started late or ended early) can be decoded.

This raises an interesting question in my mind. Not that it would be a good regular operating practice, but is it even possible that a transmission could be started (say a final 73 message) and then at about 6.5 or 7 seconds in, a decode could be double-clicked to call that station, and BOTH messages would be decodable? Or is the minimum time required for a decodable transmission simply too long to allow for two? If length of text affects time required to transmit, then my short call might contribute to being theoretically able to combine two messages. My final 73 to a 4-character callsign would be just 12 characters, and a TX2 message would be just 13.
