Bovy gets her the cow data from your DHI file that is sent to us.
So unless you send generated DHI files more often, it is only as up to date as of your last test.
But the intervals - days in milk, days open, days since last heat, and days carried calf - are always correct for the current date. DIM and the others will be one day higher when you look at your herd tomorrow, so you don't have to make any adjustments in your head.
How many days is that ?
