Because everyone knew (it was announced as a marketing point) that the LMB pellet was made to match a ground up RT. That is where the formula came from. Purina (Mark Griffin) took a RT ground it up , extracted the water and reverse engineered it and then matched the breakdown (protein , amino acids ,lipids and carbs) with ingredients to make the LMB pellet. They don't say X pellets equal one RT nor do they give the caloric breakdown.
