I used to fly close to 140 hours a month as a CFI. Roughly 7 hours of block per day and 6 days a week. Sometimes closer to 6 hours a day, sometimes closer to 8. Very busy school that had
me booked out a month in advance so no “block” was every empty in my day. Little to no ground school as they used some Cessna ground school program they sold that we could track their progress.
