Is this the Trutine of Hermes or what?

1
Hello, everybody!

I was scanning through some old documents of my grandmother (which was an astrologer) and I found a brochure of hers with a technique that looks like the Trutine of Hermes, but at the same time seems to me very different. I would like to know if anyone knows what this may be about... The brochure says it is used to find the prenatal epoch and to rectify the chart...

It is comprised of 13 steps (with 7 additional ones if you make manual calculus). The steps ask to find the moon, the asc and dsc (as expected, nothing unusual here), but then it starts (in step 6 on) to ask for sidereal time, to check the table of houses (Raphael's), to add or subtract GMT time, to use a table of logarithms, the "step of the moon" (how much the moon 'walked' in a day).

Anyone know what is this all about? Is all that necessary to rectify a chart with the Trutine?
