Shimano 12 speed b-tension screw guide

My rear derailleur was delaying my upshifts down the cassette quite a bit. I was having to double shift and then shift back down one to keep riding. At home I replaced the cable and housing since I found the cable frayed. It was a year and a half old so it was more than due. Shifting was much improved but I was still having issues. I set the limits and started messing with the b-tension screw but couldn’t get it quite right. So off to the internet to educate myself. Turns out my derailleur cage has this handy little line on it to help properly set up the b-tension adjustment! I hope this helps someone.
P.s. Sorry for the grimy drivetrain. One ride on a freshly lubed chain without a wipe down afterwards.
