ÖKOfen calculation Flow temp See setpoint

Hello,
On Pellematic compact 18KW with pellematic touch (Insulated 1900 house, Eure, 11 radiators, 200m2)
In the water law adjustment phase (no ambient influence)
I never manage to find by calculation the figure of the T° Setpoint departure Cf . Thus: in a well-stabilized regime:
Water law: 31,5 and 1,1
Outdoor temp 13,9
Comfort temp 20,6 (auto mode), measured 20,3
Flow setpoint temp Cf: 33,9 (measured 33,7)
When I do the intuitive (dumb?) calculation: Starting setpoint T° = 31,5 + 1,1*(20,6-13,9)=38,9.
I always find about 5° above the boiler flow setpoint temperature.
Does anyone have any light on this subject?
I attach a graph file.
Thank you in advance
Jean-Marie
