It just what I heard. But if imjolly says it works, they I would take his word as correct.
keith when I first tried it I was getting help from RogerB and once I had improved my connection tweaking to 75% gave me NM of 4 instead of 6. I think mine has now been lowered as part of the trial and instead of about 3 I am about 2 due to 75% and holding. It does get quite low about 11pm but holds so might increase to 80% if I start getting drops in connection
