Appologies for the delay, did I ever reply….? Just checking the forum for the first time in a while. I’m afraid I have been out of the scene for a couple of months due to a horrific multiple fracture of my right arm. Bones sticking out in all directions, it was pretty gruesome! Needed several ops and I’m still in a cast!
However as an alternative source of information immediately the most excellent Nemetode website at
have the technical notes here explaining just about everything!
Hope this helps.
