I looked again at Proluna. I think I now understand the problem of the person on Facebook.
"...pero pero a la hora de hacer Retorno Solar sigue tomando Años y No meses!"
This is probably about RESONA. You take a solar horoscope and let the ascendant run with 30 days per house, as 1 year for the entire cycle.
The Proluna system (7 years per house) also includes 3 other sub-rhythms. Here is another link:
https://spinelli-astrologo.blogspot.com/2018/08/sistema-proluna-de-astrologia-nro-4.htmlI have learned, Proluna is as common in South America as Huber in Switzerland and MRL in Germany.
So with the new module with free choice of time, Proluna users could use the entire system.
Unfortunately, I found in the proluna module that if I use a different house system, nothing changes during the triggering. The annual ring when you press Draw is also the same as with placidus.
