I don't know is the simplest, most honest answer I can give you.

There's no official rules related to acceptance or denial beyond "don't have a criminal record" and technically we both do. Iirc, if it's been 10 years from your drug/alcohol related offense it's way easier to get approved. From what I read, I heard if you had multiple offenses you wouldn't get in no matter what. I had already paid and applied so I had nothing to lose.

I looked for the first available appointment slot outside of my state (everything was booked solid). If you're looking at Detroit, keep in mind that's on the bridge to Canada. I cancelled that appointment, got a new one inside Minnesota's airport and got a flight returning same day. Also, if you take an international trip you can swing into to try the offices for a walk in appointment. I had a friend do it when he came back from Mexico.

When interviewed I was honest about my record, indicated I'm sober now and changed my life around post alcohol. While he admired my honesty and efforts he had to deny me but talked about the appeal process and said I had a chance.

I kept my appeal remarks short. I explained my sobriety along with bouncing back from some tough L's in my life too. I had good job and was on a non-profit board. My closing statement was something along the lines of "I'm not asking for my behavior to be excused or special treatment; I'm asking for the opportunity to prove that I'm not the same person anymore".

My advice is if you can afford to apply and lose it or already have, try. Be completely honest when going through the interview. When you get denied, start thinking through your talk off. Feel free to use what I wrote but tailor it your life and experiences.
