Two small updates, I got a better picture of the new angle on my kammback:
I'd say I'm there, until I go for a bit more length.
Also, I was getting a vibration from my passenger side and investigated it, found one of the sliders on my brake caliper completely stuck
I took the car out quickly after cleaning it up and regreasing it, and it seems to coast even better now! If that caliper was sticking a bit, I can't wait to see the FE on my next few tanks
