Hi USR,
Since Jaimini has the simplest techniques to assess life span, and due to some reason I was overall worried about the life span of mine and my sister.
So i had calculated it using the jaimini technique, we both fall in the alpa ayu category.
I will tell you how i approached it, in my case the set of (Ascendant[vir] + Lo of 8th Sign[vir]) falls under Madhya Ayu category. Next set (Asc[vir] + Moon[lib]) falls under Alpa Ayuu, and the third set (Asc [vir] + Hora [lib]) falls again under Alpa Ayu. When you have 2 of the 3 sets pointing to one category then we can take that as an answer.
If all 3 sets are in different category then we have to rely only on the hora + asc cateory* (only caveat is that if moon is in 7th or Asc then use only Asc + Moon)
Astrology has been a hobby and I dont know Jaimini sutras much as I never went in depth into it, as other branches like KP and Ashtakvarga interested me more. But due to simplicity for lifespan calculation I used Jaimini in my case.
Please share your opinion on the same, and you observations with Jaimini Lifespan technique.
Regards,
WS
