Question about Basal Rates and Pumping?

If a basal rate is for instance 0.50 units/hour is it given all at the beginning of the hour or divided up over the hour given every 5 or 10 minutes? I should probably know this but don’t. Thank you. The pump is a medtronic paradigm. Thanks again.

It is divided over the hour. Different pumps divide it in different increments.
