the cardioload graph only shows the last 5 days and sets everything to 0. I saw this at zero for the first time on October 26. Since then, it has been moving up every day, now everything is 0 before 12/11. If I set the graph to 3 months, you will see data up to 8/10. Measurements are taken with a Garmin venu3 and synced via Apple Health (iPhone 11)
