Adding multiple values in a single row using tableadapters?

Database technology is advanced and powerful enough that you don't need to repeat the data 8 times. You can store the data once then create 8 rows with just the data that is different for each cycle time. You can do it the way you are thinking, and repeat the data, but are you interested in doing the more efficient and flexible manner that I describe?

I don't know what you are using to interface with the database. Have you created a data source and TableAdapters? In order to get the most useful answers and if you want to repeat the data as you describe, then you need to provide the information about how you are interfacing with the database, such as if you are using TableAdapters.
