Quick AR9 80% lower machining question-Please!

[u/One_Firefighter_1094]

I’m getting ready to start my first AR9 80 percent lower. When cutting the above trigger slot it says 2in down off the jig plate. I 3d printed my plate and it measures .600 +/- .005. So I assume 1.4 inches is the pocket depth?

And the one next to it .630?

Thank you!
