1.3 Notes 14:08, 31 March 2015 (UTC)Freyberg 14:08, 31 March 2015 (UTC)

 + Review of the 2011 FSD note, see attached.
 + 2011 FSD note manually included the C100 data, there was only one
   zone at the time.
 + Need to incorporate C100 FSD data into the same FSD data flow as for
   the C25/C50 modules.
 + Analysis requires lots of interpretation, it this, then it was that;
   if this and this then it was that.  Rather messy.
 + C100 trip recover is now less than 2mins.
