It has cut the throttle several times, almost causing two accidents over the past month. Over the past month I have used nearly 2.5 tanks of 87 octane gas, because the dealer inserted that gas and my dad refuelled the BRZ without my knowledge with a 1/2 full tank.
I'm finally putting my "foot down". I got my mom to scream and nag until my dad complied. Now I'm filling the tank with 92 octane from Costco tomorrow, with about 1/8 tank of 87 octane left over from previous fill-ups.
I'm hope to create a discussion in the next 3 weeks on my observations before and after, taking into account mpg, dollar/mile, throttle cuts, performance, and perhaps feel of the car. I hope for the best.

I don't usually call names, but your dad is being an idiot. Running an engine below it's required octane and causing it to knock ON PURPOSE is the dumbest thing I've ever heard. That's damaging the car on purpose to spite an extra 2-3 dollars a fill up, on a sports car that gets insanely good gas mileage. Wtf. Honestly, I'd get a job so you could afford to put your own gas in it.
