Ouranos thanks for your consideration I put it out here for people to experiment with as I have found it interesting.
Going back to Amy Whitehouse the technique at time of death is 12 Sag it enters the terms of Venus which is maltreated by Mars by contact, both Mars & Venus are Munakara & triplicity rulers of the 8th house.

The Age Point in Astrology and the Author Franz Kafka at astro.com The Age Point (AP) is a method developed by Bruno and Louise Huber. It is based on the assumption that the natal chart has a time dimension in it and behaves like a clock, the 6-year cycle grew out of Hubers’ research.

This is almost exactly what I have been describing here only differs in that I use whole house so it doesn't start at the Ascendant like Hubers method & a slightly longer time unit, but other than that it is the same.
