TopTup : the forum is not my profession, it appears to be yours though! Didn't have my head in the sand, but was busy on a long roster. Don't have internet access always, and even if i did, i'd come here after i've chatted with my wife n kids. Will take it up with you on PM once I'm back. The 131 pattern is a long one.
jstars : Checked the PM. I've already put this up in advance for the monthly commanders meeting. I hope to get answers then. Your friend will also be present at the meeting (I hope, since I see him rostered, but then rostering is another story). Will chat with him directly on this.
