77/90 is what I expected.
All bodies consider exercise to be stress from a data standpoint and the #Oura doesn't really differentiate between good stress and bad stress. It's just looking at your heart rate data. This is why you still need your own manual correlations and understanding of your own body. Numbers are just numbers without correlation.
My body is recovering from 2.5 hours of exercise yesterday so 77 is not bad for MY body.
