Their methodology of allowing the herd to function independently and then focusing data collection on health issues and consistency is the right idea here. You want to measure time spent caring for the herd against time spent perform actions to continue to collect milk from the herd. It's a balance, but if you can get more efficient human time spent caring for the herd (good health sensors!) then you're always going to see a happier cow.
