I sorta do. I have all that info in front of me but I mostly use it to stay under control in the early stages. If I see too high of a number I back off.

But once I'm in a groove I use perceived effort as much as possible and just spot check it against normalized power which will pop up in an alert every 10 miles.

Worrying too much about power or HR can get me in a hole sometimes. Maybe it's just avoiding the mental fatigue that helps, but I tend to race best when perceived effort is my main indicator and all else is tertiary.
