I am seeing the same thing, I have been moving the offset to see the results, Yellow real-time COP and Blue is an average COP over 5 mins.  
I know its above and beyond what is expected of a home user but we are particular and like the data, I have implemented my own Ground floor temp control with Home Assistant - you can set your own hysteresis, set and target temp, cycle etc, you can use any temp sensors IP, Zigbee, Z-Wave place them around the house to get an average, it would cost less than £50 and a bit of time to get exactly what you want. Link to my trail below if anyone is interested?

> I have been experimenting with ‘Pure Weather Compensation’ ie no external controls. It’s been very successful at heating our house maybe a bit too much, our 8kW unit can modulate down and consume a small amount of steady state electric ~300W but the house is still too hot (especially upstairs) even after throttling/balancing the radiators, I guess there is such a thing as a too well insulated house. So i am now experimenting with a hybrid model and using Home Assistant. 1st I take an average …
