Round ratings or leaderboard scores by age

I really enjoy the new round ratings, and ive always liked leaderboards. Bit i am a 70+ player and dont have a way from leaderboards or round ratings to compare with others in my age group. If i get close to a 200 round rating, im excited, but an intermediate player in their 30s probably wouldnt be so excited. How can i compare these to my age group?
