Freezer stash?

I pump every 4 hours give or take. Usually 12am 4am 8/9am 12/1pm 4/5pm 9pm then 12am. My 7 week old eats 3/4 oz every 3 hours.

When I pump I get between 5-8 oz each time and I’m able to freeze 5-10oz a day.

1. Is my output more than normal or am I normal?

2. I have 500oz in the freezer today. Is that average for 7 weeks on or should there be more?

My goal is to pump till she’s able 7/8 months then just feed her frozen milk till she’s 1. I just want to make sure I’m on the right path with amounts or if I need to add a pump or start taking something to help make kore milk
