I dont tend to see these points as completely separate. The general impacts on the specific. In other words if you hold to a rapid explosion type theory based on almost exclusively Greek ideas that inevitably affects how you perceive the development of specific techniques.
I agree, and I don't see the two issues as separate either. I just wasn't sure if you were thinking of some general historical statements that I made at one point in time, or if there was some specific technical argument that I made which gave you the impression that I was a strict 'sudden inventionist', such as the post about the origins of the exaltations on my blog for example.

However, in regards the provenance of techniques I do feel there is sometimes a tendency to overemphasize the unity of early hellenistic astrology and underestimate its pluralism. House systems is just one example.
Yes, this is definitely a prevailing tendency at this point. Certainly it has its pros and cons. I think that some of the work that can be done in comparing parallel passages in different authors and identifying common sources raises interesting pieces of evidence for a sort of continuity, and it can also help to explain points of divergence in the tradition. However, the view that the entire tradition was completely unified and coherent in the beginning but then sort of devolved from there can lead to a sort of technical and conceptual myopia that forces one to downplay or overlook areas of discontinuity or divergence. Somehow there has to be room for both approaches.

On the historical issue I am not sure if I like using the label 'gradualist' . This implies astrology moves forward like the glaciation process. Incredibly slowly and imperceptably. In contrast to this I think astrology has had many periods when its techniques have taken a progressive spurt forward. What I question is whether the the undeniable leap forward astrology took in 1st or 2nd century Alexandria was based on an almost totally indigenous hellenistic astrology or whether it was the product of the creative cross fertilisation of Greek, Mesopotamian and Egyptian ideas.
I don't think that anyone really doubts the indebtedness that the Hellenistic astrologers had to the earlier Mesopotamian and Egyptian astrological traditions. I think that the main question is exactly how much was inherited from the previous traditions, versus how much was developed subsequently from the synthesis of those traditions that occurred in the Hellenistic period. Some degree of cross-fertilization is a given. However, that does not tell is if the Mesopotamian astrologers had developed a full-fledged aspect theory, if they used houses, planetary rulers of signs, time-lords, etc. That is to say, aside from the techniques and concepts that we do know were inherited from the earlier traditions (the zodiac, decans, twelfth-parts, natal astrology, etc.), what do we say about the techniques that do not have known traditional antecedents?
From what I understand of Hand and Campion's thoughts on this matter, they argue that many of these techniques must have been developed in the late Mesopotamian traditions prior to the visible advent of Hellenistic astrology, and that it is only through the loss of so many cuneiform and other sources that the advent of Hellenistic astrology appears to be such a sudden and drastic departure from what went before.
On the other side of the spectrum, those that argue for more of sudden invention accept that a synthesis took place between the Mesopotamian and Egyptian traditions, but that beyond that there are far too many subsequent technical and conceptual innovations that have little to no known precedent in the earlier traditions for them to simply to have been inherited wholesale. Most importantly, they argue that the systematic character of these developments implies that they were consciously or deliberately constructed in some way.
The whole debate really rests on just a few key issues, the majority of which we may never really be able to fully address due to the loss of early sources.

I think the rapid development theory focusing on purely Greek sources ignores a lot of historical evidence to the contrary that states Greek astrology was heavily influenced and indeed founded on Mespotamian astrology. If this was not the case why are so many classical sources repeatedly telling us this? Is it more likely a 1st century writer has it wrong or a 21st century scholar trying to put together the historical jig saw without many of the original primary sources?
The ancient views on the origin of tradition are a pretty tangled problem in it of itself due to a number of factors, and I'm not sure that the statements from the ancient authors themselves can always be taken at face value. Some authors do present more of what we would consider an accurate historical account of the origins of the tradition, either attributing the development of the science to the Mesopotamians or the Egyptians. However, there are just as many who present a more mythological view of the origin of the tradition, likely due to the pseudepigraphical works attributed to those figures at the time, tracing their lineage back to Hermes, Asclepius, Nechepso, Petosiris, Zoroaster, Abraham, Orpheus, etc. From that perspective I do think that we might be in a slightly better position to reconstruct the actual historical development of the subject, or at least make inferences from a broader historical vantage point.

To some I extent I fear current debate around hellenistic astrology is too inward looking and too narrowly focused on hellenistic astrological texts. There is a risk this may be mirroring older scholarship on the history of astronomy which gave all the credit to the Greeks at the expense of the Babylonians. For example look at J.L.E. Dreyer's ''A History of Astronomy from Thales to Kepler" . Its a great book and very useful. However, as a lover of all things Greek his attitide tended to grossly underestimate the role of Babylonian astronomy in influencing Greek ideas.
I agree. One issue is that while some cuneiform birth charts have survived, we don't really have any technical manuals on astrology from the same period - the period after the advent of natal astrology. One of the things that people get caught up on is the fact that the extant Cuneiform birth charts just list a few planetary placements and then don't say much else, which doesn't give us much of a clue about how they actually delineated charts. What is interesting is that we would be in a similar position with the Hellenistic tradition if it was only the Greek horoscopes that had survived, since the vast majority of the non-literary horoscopes only list the placement of the planets in the signs and then say something curt at the end like 'good luck!'. Obviously this is because astrological consultations in ancient times, just as today, were primarily done orally, not written out. If it were not for the fact that actual technical manuals such as the
Tetrabiblos or the
Anthology survived into the present day then it would hardly be apparent from the Greek horoscopes how astrology was practiced during that period. To some extent we have to keep in mind that it is likely a similar case with the Cuneiform horoscopes.
