Have used a powermeter for last 6 years I’m a triathlete and it is a tool that I wouldn’t be without. As you have said it is pointless unless used effectively.
i know my Ftp, np, atl, ctl, blah blah blah the above post is what I’m after how and what you use off road.
Cheers my first post possibly to vague but I didn’t want to get into terms and numbers…
