Return lowest value pair for Blood Pressure

Hi, I'm trying to do this generally with a group of several BP values across a single row, including TOD, systolic, diastolic, and heart rate, and I'm stuck on this rather complex set of functions. I'm using Microsoft Office 2021 on Windows. What I want to do is to evaluate each group and record the group with the lowest diastolic within what might perhaps be a single lowest systolic (lowest systolic being the most important), then keep these in an additional right-most column group on the same row. I have all this set up currently where I take the average values from all entered groups (some may be blank), but need to change it to the group with the lowest systolic/diastolic during a single day, a day being a single row. I just can't make it through the example given below, having set up the original average function many years ago, and out of practice with Excel since then. Thanks for any assistance!
