partivartana yoga effects in others graha sambandha

Hello, Ernst . Can the results given in the parivartana yoga course be carried over to interpretations about the very close conjunctions or oppositions in the chart? . for example, a person who has a 4th lord and a 5th lord has karma to find happiness in creativity or a person who has a 10th lord  and 8th lord  may have changes, career difficulties, or continuing the parent's business; I notice some of these effects in the lives of people whose charts I read had strong conjunctions without necessarily exchange (parivartana). I know that sambandha kona and kendra form raja yoga, but the descriptions in the parivartana yoga course are great and I would like to know if I can apply them in conjunctions or oppositions as well.
