I do track the price per unit (kg, lt, etc) and I was a bit on the fence on whether I should show and graph that number instead of the price that someone would pay at the checkout, but I opted for the latter to keep it more "familiar" with the prices people see. Having said that, that's definitely something that I could add and it would show when the shrinkflation occured if any.
