I think that 10 seconds or longer is a poor use of on-the-air time unless its a very robust FEC mode. Also, as many who have observed, the ionosphere can change much in 10-20 seconds.

The time from start of transmission until receiving the first data segment is 10s to 15s. That's the sync-zone, the lead-in. 20 sec is not to be taken pedantically, it may be 15.2135 sec, HI but the magnitute is NOT in the 2 sec range.
