The psk-data  base   has  a series  of  TX beacons 
 
one shows  Tx beacon at   18:48
 
18:48  + 32  mins  =    19:20
 
19:20 +  ( processing  time  2 ~5)  =  19:24     which is the  time  stamp  of  the  X 4   detections  ?
 
Only   40% of the  Tx   is required  to   produce  a  decode/detection  .  12  or  13 mins  of   Tx  time   in the  32  min  period ,  random or  block
so  a  short  Tx  will  produce  a  low  s/n  detection  ,  the  s/n is  the  average  along  the  time  line  ,  so  50%  will  be  - 3 dB  lower than   100% etc
