in addition to this comes the Estimated value of Sky Clear value 0 to 10 (0=Overcast, 10=Clear)
so that a single day may have a maximum of 40 points.
These points are then calculated as Percentage.

Example day: Temp. 4,5C (3 pts), Precip. 3,5mm (9 pts), Wind 4,0 m/s (9 pts), ClearSky 30% (3 pts):
Total: 3+9+9+3=24 pts = 24/40 = 60,0%
