My 150 costs me very little to operate why use a
simulator when I have the real thing available maybe it will take
longer but
I feel I will get more skill actually flying then in a simulator.

Actually, I think you are off base there. There are things you can do
with a sim that you can't really do with the real airplane in terms of
system failures. Only thing is, certified sims (at the light GA level
- I'm not talking about the stuff with visuals and motion) are a waste
of time and money. They are inferior training tools to Microsoft
Flight Sim. No, you can't log the MSFS time (except as ground
instruction) but it's quite valuable - and a copy of MSFS costs less
than an hour in one of those sims.

BTW, I see nothing wrong with using a C-150 for IFR training. It's not
really a practical IFR travel machine, but it does fine if you want to
make hundred mile hops in benign IMC.

As for max 3 in a day - yes, usually, but I've had a student who was
able to handle more. Only one, though.
