Yes, I agree - I should have added some comments about this.
In Message of the Stars
"This axial rotation of the earth brings a new degree to the zenith, or Meridian about every four minutes, and by the rules of one system of progression we may calculate how many degrees of Right Ascension come to the Meridian position from birth to the formation of a certain aspect. The intervening degrees are then converted to time at the rate of 1 degree equals 1 year.
The other system of progression is founded upon the orbital revolution of the earth, but in this system the positions of the planets are expressed in degrees of Longitude and measured on the ecliptic or Sun’s path, from Aries 0 degrees to Pisces 29. The measure of time is the same as in the system first mentioned: 1 degree equals 1 year, but there is this important difference, that while the earth takes only 4 minutes to turn 1 degree upon its axis, it requires 24 hours to move 1 degree in its orbit. Thus, by one system of progression all the aspects that govern events in a life of 60 years would be formed in 60 times 4 minutes, which equals 4 hours or one-sixth part of a day. By the other system, formation of aspects for the same period of life would require 60 days, or 2 months, or one-sixth part of a year.
"... 1/360 part of a day being equivalent to a year, that an error of 4 minutes in the given time of birth would throw predictions out a whole year. Few people know their birth hour to the minute, therefore this system of progression is of little use and little used."
By this method [1 degree equals 1 year] an error of 2 hours in the given time of birth would only cause an error of 1 month in predictions; this system therefore gives universal satisfaction, and is most commonly used."
In Simplified Scientific Astrology, Heindel preferred to call "1 degree equals 1 year" the Primary Directions, and because of the importance of the Progressed Moon, he referred to this as a Secondary Direction. This of course differs from Nicholas Devore's summary of Directions in his Encyclopedia of Astrology, but seems to agree [somewhat] with Alan Leo - "The other or secondary system, primarily intended as an aid to the foregoing, is purely zodiacal, and was much in favour with the Hermetists and Arabians, hence it frequently goes by those names."
Alan Leo - The Progressed Horoscope
"Directions proper are of two kinds: Mundane and Zodiacal; primary directions, strictly speaking, belong entirely to the former and so-called secondary ones to the latter, i.e., one is made according to the circle of the zodiac and the other according to that of the world, or in respect to the mundane distances of bouses and angles.
(1) Primary arcs are constituted by the diurnal motion of the earth immediately preceding and following the birth; and it must be conceived from the commencement of the study that the planets' places at the moment of drawing breath only are dealt with, they having all the efficacy impressed upon them of the heavenly bodies which have moved away. So that it will be comprehended that the Primary Directions for a lifetime are formed within a very few hours after birth by the diurnal motion of a planet or planets, either bodily or by aspect, to: (0) the angles; (b) to other planets; (c) to its own or another planet's original place.
These are considered the most powerful agents in the production of events, but their calculation entails patience and a certain share of mathematical ability, two things not always at the disposal of the ordinary student.
(2) The other or secondary system, primarily intended as an aid to the foregoing, is purely zodiacal, and was much in favour with the Hermetists and Arabians, hence it frequently goes by those names.
It is based on the daily motion of the sun, moon, and planets subsequent and antecedent to birth, possesses undoubted power, and appears to be the method which finds most favour in the eyes of the modem astrologer; perhaps this is scarcely to be wondered at seeing the rapidity at which the age lives. This method is, in fact, that of the " progressed horoscope," to which the previous sections of this work have been devoted."
Nicholas deVore - Encyclopedia of Astrology
The Primary System is thus a calculation of the number of four-minute intervals during which a given planet will move from its birth position to the place where it conjoins or aspects a sensitive degree - usually the birth-position of some other planet.
Secondary Progressions, much easier to calculate, are based on the theory that the positions of the planets on the third day of life, for example, will represent a correct Progressed horoscope for the third year of life, and so on. In this system one casts a Progressed Figure for the year desired, by casting it for that many days after birth, using the ephemeris of the year of birth.
Re Solar Arcs
I have used them occasionally - I prefer the other method, although I do believe that the Solar Arcs do provide a different kind of information.
@Dubyadude1986
So, is there any chance we can turn any of these actors into real astrologers?
Well your comment deserves a response.
Are you implying that "old-timers" like Alan Leo 1860-1917, Sepharial 1864-1919, Max Heindel 1865-1919, Evangeline Adams 1868-1932, Llewellyn George 1876-1954, Alice Bailey 1880-1949, Charles Carter 1887-1968, Marc Edmund Jones 1888-1980, Dane Rudhyar 1895-1985, Cyril Fagan 1896-1970, Reinhold Ebertin 1901-1988, Grant Lewi 1902-1951, Charles A. Jayne 1911-1985 and Ronald C. Davison 1914-1985 were actors instead of real astrologers?
Many of these people incorporated Progressions into their Interpretations, and were careful to observe the workings of the Progressed Moon and Lunations along with Transits. What other techniques would they use in terms of the timing of events?
Or are you just implying that me and possibly Frisiangal are actors because we respect the work of Max Heindel and Alan Leo, et al?
I can understand that there are people who scoff at the Rosicrucians, especially their Philosophy of Astrology and their affiliation with Mystic Christianity. Did you know that at one time the Rosicrucian Ephemeris was the most popular Ephemeris in the Western world? - and it still exists today.
These old-time astrologers were instrumental in getting astrology of out the "medieval" times and into the Modern Era - they also incorporated Uranus, Neptune and later on, Pluto into their Interpretations.
Any contemporary Astrologer owes them a debt of gratitude.
Do you think that Stephen Arroyo, Zipporah Pottenger Dobyns, Michael Erlewine, Jeff Green, Liz Greene, Robert Hand, Isabel Hickey, Maritha Pottenger, Erin Sullivan, Richard Tarnas, Karen Hamaker-Zondag were not familiar with the work of these "old-timers"? Any reputable school of thought has to have a solid lineage.
Here's a brief quote from Robert Hand
"But then with Alan Leo, and more recently people like Dane Rudhyar, and on another level people like the Hamburg School and Cosmobiology of Ebertin, a rather new kind of astrology began coming into existence, which it might be appropriate simply to call 20th century astrology, but I would like to call modern astrology."
The biggest difference that I see from the "old-timers" compared to contemporary astrology - is that more modern astrologers are paying more attention to the Nodes of the Moon.
As this thread concerns the correspondence bewteen Natal aspects and Transits perhaps you can share some of your experiences regarding this topic.
....................................................................................................
Here is an example of a series of four Lunations and how they corresponded to Natal aspects of Sun square Mars, Sun conjunct Saturn and Mars square Saturn. In addition there was also a series of Transit aspects that corresponded to the Natal aspects and Lunation aspects to Natal positions.
It shows some of the timing involved in this Saturn Return.

1st Row
The lunation on 08/08/1983 at 15LEO40 was opposite Mars and square Saturn and the Sun. It also triggered the TMars opposite Mars, and the TMars square Saturn at the end of August 1983.
2nd Row
The lunation on 11/04/1983 at 11SCO56 was square Mars and conjunct Saturn and the Sun. It also triggered the TSaturn square Mars and TSaturn conjunct Saturn that occurred Nov 22 1983 and Dec 4 1983 respectively.
3rd Row
The lunation on 02/01/1984 at 12AQU19 was conjunct Mars and square Saturn and the Sun. It also triggered the TMars square Mars, TMars conjunct Saturn and TMars conjunct the Sun that occurred during the first week of February 1984.
4th Row
The lunation on 05/01/1984 at 10TAU58 was a Solar Eclipse and was square Mars and opposite Saturn and the Sun. It also triggered the TSaturn conjunct Saturn, that was in place May 1 1984
Re 4. the "<05/01/1984" indicates that the Transit was already in place.
