The question to ask when tracking to optimize reoccurring bills for home and grocery is if there is even any room you can give anyways.

You'd probably find the easy end actionable changes better by tracking the amount and which food spoiled before eating, or by testing your standard basket item costs at different stores you are willing to go to. But all of this isn't something you need to do continuously. Once you figure it out, you should be good for some period of time.
