I started recently to run with chest band for zone 2 HR. My default hr for zone 2 is up to 132bpm on Garmin.

This feels too easy to run. When I was running zone 2 "by feel" I had pace 6:15, when I watch HR up to 132, I do 7:15min/km. I was curious what AI will say and answer according to AI is maximum value for zone 2 should be around 135-140 acording to picture. Not sure how to redo my zones exactly, any advice?

Picture I post is my first run on hills, I did not push until maximum HR
