I believe SagiCap is right in her feeling about conjunction-effects in real life; as I have state elsewhere here on AW, the "quality"/"strength" of the (longitudinal) conjunction (and I am referring to partile conjunction) I believe is conditional on a number of other concommitant factors, and I have come to regard the position of each planet in the longitudinal conjunction relative to the ecliptic (its side-of-the
ecliptic declination) to be the most important of these: if both planets are on the same side (North or South), that "strengthens" the longitudinal conjunction and its implications/ramifications; if on opposite side, that "weakens" the conjunction influences: along these lines I also have come to consider that if the conjunct planets are also in parallel or either declination or latitude, that conjunction is amped up; but if the conjunct planets are also contra-parallel, that conjunction's influence is diminished (in some cases I have looked at, significantly so)
I have no historical literature sources to "authorize" this outlook, it is my own, but over the years I have become more and more convinced that I am on the right track...
