Ideally you want 30 hours in a 4-day, 24 hours in a 3-day, 16 hours in a 2-day and so on. 30 in 7 days is the legal limit. You gotta be gone for 4 days so you'd rather spend them flying & making money rather than in the hotel or airport. You'll likely never see 30 hours in a 4-day trip. If you see 27 or so hours..... it'll probably be flown by a senior crew. The reserves and junior crews get what's left over and they're often inefficient, or weekends, or early report & late finishes, non-commutable, etc.
