What’s the lowest rating you’ve seen someone get who retired after 20 years of service?

I’m just trying to get an understanding of what rating people got after doing 20 years. Obviously, everyone is different. I’m just looking for trends. Is 100% common? Is it common to only get 20-30% after so many years? I’ll be retiring soon (couple years) and it won’t be long until I start the VA process. Just looking for a general idea of what % you’ve seen in you and or your friends’ rating specifically after a full 20+ years. Thank you!

Edit:

Of course I’m not asking what you think I will get with zero info given. And I’m not saying I’m entitled to anything just because of serving over 20 years. I’m just asking what you’ve seen because I’m curious. Trend analysis. And I know that someone who served one year can be much more disabled than someone who has served 30 years. I’m just asking out of curiosity. Thank you!
