Only if the knock sensor detects "pinging", otherwise the timing
will remain the same as it would with premium gasoline. Of course,
since the engine isn't allowed to ping the driver will probably
never know if the timing is retarded or not, so unless you're
driving to win an economy champion****p you'll probably be driving
around with retarded timing.

Er, no. A couple of problems here, no loss of power OR fuel mileage if
you can drive gently enough to avoid retarding the ignition and, more
im****tantly, are there gentle drivers in Miatas and, if so, WHY? ;-)

Agreed. It makes no sense to not have the power and economy that is
available just to save a penny. If you want to run regular get a car
that doesn't recommend premium.
FWIW, I used to own a car that absolutely had to have premium but that
was when gas was cheaper, I'm glad I don't have it today. That's
something I check and if a vehicle recommends premium I'll go look
elsewhere, it's not worth it to me.
