4. Keep your interim results

It's important to remember that optimization is rarely absolute, especially when the "profitability" factor has been integrated into the results matrix.

Indeed, if your cost price includes, for example, a material cost, an energy cost and a labor cost, it is unlikely, based on recent experience, that these three components will vary in parallel and identically.

There may therefore be some advantage in keeping the intermediate results of this experimental approach, and updating the conclusions where necessary.
