To find your best recommended baby imprint interval divide the number 1 by your maturation setting. Using that number will give the ability to 100% imprint roughly 99% of all dinos. The vast majority of servers will double that number in order to have a longer window of time between care. Doubling the number allows for roughly 80% of dinos to be 100% imprinted. (Only the small unimportant dinos miss out)
