I need help to create a definition with LB to get the number of days of the input geometry where the sun shines for at least 8 h.

I use the LB sunlight hours and sunpath-diagram components with a conditional statement to retreive the sunlight hours for when the normal radiation equals or exceeds 120 W/m2 (the definition of sunshine). But then I want to see how often it shines for a particular period per day. The unit I seek is hence the number of days where a minimum of 8h sun is shining (960 W/m2/day (8h/day*120Wh/m2)) simulated on the Rhino-model.

Thanks alot in advance!
