Milk production = Sum of milk production measured by milk measurement on robot, including separated milk (e.g. colostrum, penicillin)
Remaining time = 24 hour - Total milk time
Milking speed and Duration: Not every robot brand has milking speed or duration in their data connection. Lely, GEA, DeLaval and Fullwood do but Boutmatic and SAC don't.
When the column is empty, this means we don't receive that data.
