Trying to get average of all Records in a Database I'm keeping for Diabetes.
I have database for Glucose reading see screenshot:
In this A1C is devided by days which is sum of Day a Serial Number.
Actually there are 3 entries for each
So Days should actually be 35.67 into the so the totals of all the entries (Breakfast Reading; Lunch Reading: Dinner Read) should be devided by 35.67 in this case)
A1C equal average of all your meter readings over a 90 day period
I can upload the aqual file to DropBox, Sugar Sunc or even MS SkyDrive.
