I never implied my cardio fitness was poor, just that some metrics are relatively better than others. My RHR (currently 47-48 per various fitness trackers) has always been pretty elite. I don’t think about it and it doesn’t change much except in response to stress. I’m more interested in getting into the 90+ percentile range on the cardio metrics where I’m closer to the average. I don’t obsess over it, it is just interesting to see how different activities that I was going to do anyway move the needle.
