When I learned, our instructors did about 100 hours a month.

It was 7 days a week, 8am to sunset Monday to Saturday, late
start at 10am on Sunday. Usually flying with 2 students, 2 lessons
each a day, 1.5-3 hours each depending on whether it was exercises
or cross-country...though it wouldn't turn out to be 4x3, more like
4x1.5, or 3x1.5 and 1x3 or something like that. Days off weren't
a problem usually if an instructor wanted it at any time as long as
his students were ok with it.

Ground school was whenever they had some free time, between
lessons or evenings, though there wasn't much ground school, mostly
just explaining and debriefing lessons. Other stuff was self-taught
mostly (read the books, watch some videos).

My goodness -- forty hours a week? Even with ground school, etc., a CFI is
not going to give forty hours/week instruction under any circumstances.

You would have to be at the office 24/7 to get anywhere near that amount
of
time.
