Heart Rate bar chart not as helpful as old HR pie chart

to the developers of Strava: I have been using strava daily for 7 years. I have never been inspired to complain, but after the change to display heart rate data as a bar chart as “percentage time in zone” rather than a pie chart with actual time spent in zone, I need to speak up. It is not helpful to know I spent “20% of a given ride at Z2” --what would be helpful is the TIME spent in Zone 2. I often do work outs of different lengths, and for example, “10 minutes” is a lot easier to think about than “20%”.  Bar charts are not an intuitive way of summarizing data that relate to a “whole”, aka like a pie chart is. PLEASE PLEASE go back to displaying heart rate data as a pie chart with actual time spent in zone. I don’t use any other workout soft ware (not training peaks, etc) and I don’t want to have to start now.
