Thanks Jon, those numbers seem reasonable and I would also assume each event 
might require adjustments.

  Hi Jerry,

  I am used to record local events. I usally record 5 min worth of data
  for events up to 600 km away. For 601 to 2000 km I usally record around
  worth of 10 min data. Anything of more distance I use 40 min. But I
  usually estimate the data needed pr.earthquake.

  Regards,
  Jón Frímann.
