The Sammohavinodani, chapter on Paticcasamuppada (PTS)p181 , refers to this sutta and notes that there is no single fruit from a single cause:
"for here there is no single nor multiple fruit of any kind from a single cause, nor is there a single fruit from multiple causes, but only multiple fruit from multiple causes. BUT with one representative fruit and cause given thus 'avijja paccaya vinnana' etc. For the blessed one uses one representative cause and fruit when it is suitable for elegance in teaching and to suit the inclinations of those being taught. And he does so in some instances because it is a basic factor and in some instances because it is obvious and in some instances because of being not shared"...."he mentioned a single cause in the passage 'diseases due to phlegm'(in the sutta above) because of obviousness,for here it is phlegm that is obvious, not kamma and so on."
Interesting, but it does not suggest, or state, (in line with the sutta) that kamma is always a factor in what we experience.
or that it is the only factor. Kamma is always an indirect factor in our experience, because without kamma no birth, but the thing is people implying everything is kamma. A stone falling down a hill is supposedly due to kamma. But stones also fall when there is no head to hit, so it'd be rather silly for the stones to fall due to kamma alone.
Btw I never said randomness or undetermined. Just not that all has to be due to kamma. I think it is quite obvious certain things will happen also if there is no being involved, if there is no kamma involved. It is just a small step to see that those things can also happen to beings as well. Like the stone falling on your head.
