deviation between "Heating Energy Efficiency" with Vaillant APP #203

I notice quite a large difference between the accumulated (heating) efficiency (COP) between the app and the integration. The COP in the app scores between 0.2~0.6 better than the outcome of the integration. Even though the efficiency calculation in the app is sometimes really slow, the difference remains. How is the calculation made in the HA integration?
