On your first point I completely disagree, paired firing is nothing more than a Tactic.
Tactics are only viable until a counter tactic is deployed.
All this has done is give advance warning to Eutofighter opponents of an extremely useful mode of operation that has suddenly had the clock started on it. Hence the Beadwindow call.
Your second point is intriguing but I am at a loss. Care to "divulge"?
GR.
