I can understand that: I have started a new campaign (had to anyway as I was one of those who were forced to do a clean load of everything with the new system) and am trying to match what was practise as opposed to what we always seem to do - that is throw everything into action in the first month, tracking day by day and minute by minute. Instead launch a new operation once every two weeks or once a month, a complex one with the intent to throw off Room 40. As far as I can tell this is what happened in reality - the HSF operated seldom, and preferably only at full force, hoping that the unpredictability of their moves would cause constant action and consequent attrition of the GF and Harwich Force. The only exceptions would be subs, Zeppies and close-in TB patrols. I think the problem is that we tend to treat a one-year campaign as if it was the one-month one!
By the way I really did like your idea of just keeping the dozen or so 'long range TB/DD' with the Scouting Force.
