Hi - Reserved heart rate zone based on RHR to adjust the zone targets

I am hoping to get a feature that I like from zepp but I think would be great here… I have a low resting heart rate and so my heart rate zones get adjusted useing reserved heart rate to calculate those zone goals… I did match the heart rate zones in Sonar but this could be a great feature to have in the app… this way as someone starts out and gets healthier the zones will continue to push them… I think this is a quick win… screen shot provided of how zepp calculates this, maybe there is an even better way but here is that information…
