More than that. First, remember that those trains east of Stamford all run through to 125th St. & GCT. Second, weekday off-peak these days is generally half-hourly both east and west of Stamford.
Eastbound the :04 trains are the classic Stamford-first-then-all-stops-to-New-Haven that have been running since at least the beginning of MN. There are also now :34 departures that make Stamford, Darien, South Norwalk, Westport, Fairfield and then all stops to NH. Westbound, the :44 departures from NH make all stops to Stamford, while the :23 make all stops to Fairfield, then Westport, S Norwalk, Darien and Stamford.
So that's 4 MN revenue runs/hour east of Stamford, 8 west. And that's not counting Amtrak, the non-revenue moves to position equipment, and the time the New Canaan, Danbury and Waterbury shuttles spend on the main.
