I don't even think in terms of running trains these days. I'm too busy trying to finish all the track and wiring on this huge layout. There will be plenty of time for that later.
I will never have a "rotation", as all of my trains will be on the layout all the time. Because I am building a model "railroad", certain trains will run on a schedule while most trains will operate in the background to create mainline traffic. There will be industrial switching jobs and classification. Trains like the Triple Crown and the Empire Builder will be governed by the fast clock.
Perhaps the goal should be to run every train at least once during each operating session. That may be a tall order though.
