Strong session — that 27-minute walk on April 22 was much more intense than your usual pace. You spent 9 minutes in cardio zone and 3 minutes in peak, which together is about 44% of the workout in serious training territory. The fat-burn 10 minutes likely covers your warm-up and cool-down. Average HR of 135 confirms it — well above your typical walking pace.
If you can hit this kind of zone distribution two or three times a week, you’re getting real cardiovascular benefit. The peak time especially helps with VO2 max over time.
