What techniques are you all using on your profiles to identify roast issues?

I have been roasting on the Bullet R1 v2 for years (2020) and never put much effort into learning how to improve via profile analysis. That changed last year as I started to geek out on roast science. I have been creating some blog posts about how to detect common defects. I am curious to hear how most bullet users are leveraging the data. Are you reviewing your profiles/curves? I know the only real thing that matters is the end result and how the coffee cups. I have seen real improvements by spending more time in the data. Curious about others.
