Interesting couple of days with the new heat pump.

You can work it out knowing your heat loss and then W/m²

 

Just use this as a baseline, you may need to extend the W/m² and the MWT - mid way between flow and return temperature.

because there is a hint the heat goes up when the temperature goes up

 

This could just be the shift settings need adjusting but at the moment, if you've got min set to 28 and max at 32, your curve is definitely too flat. What's the calculated flow temp and min outdoor air temp? And what is your calculated heat loss at this temp? You can simply calculate your heat co-efficient W/K to establish a baseline curve at all relevant temps.
