What Dorotheus did was write a didactic poem, and if we believe the Arabic paraphrase preserves his genuine preface (Ar. Dor. 1.pr.5, p. 61 Dykes = p. 161 Pingree; also 5.1.4, p. 230 Dykes = p. 262 Pingree) - and it is fairly poetic indeed -, he extracted his instructions from a variety of sources. So if we read his instructions (or rather, what are reported to be his instructions, as the original is lost), we cannot simply infer that he is referring to his actual practice. In this respect, he is indeed similar to others such as Valens.
Also, in the Arabic paraphrase there are a handful of practical examples. One of them, dated to 29 CE, is also cited by "Rhetorius", and therefore indubitably genuine. Eight more examples, none of which are cited by Hellenistic authors, are also dated for the same era, which suggests they are also genuine. Now, it is usually assumed that these examples constitute Dorotheus' own cases (which is not beyond doubt), and if this assumption is accepted, they are the only reasonably reliable indicators for what Dorotheus actually did in practice. (If one were to reject the examples as Dorotheus' own cases, then they would basically reject that Dorotheus ever used astrology in actual practice.) In the examples the whole-sign house system is exclusively used, and consequently, this is the system that he used in practice (once again: provided he did use astrology in practice, not just versified it), no matter what other system(s) he might be referring to. In this respect too he is similar to others like Valens.
Let me reiterate: I strongly believe that only actual examples can reveal what an astrologer should actually have been doing; the works on astrology are otherwise full of instructions mainly of theoretical force nonetheless. That is why I consider assertions like "astrological author A used technique T" only valid when inferred from actual case examples, but otherwise misleadingly oversimplifying.

This claim may be right, yet it is still a fact that all the extant charts before ca. 500 that provide any insight into the issue are analyzed as though whole signs are being used, even if the astrological authors could have invested some time into further calculations before publication. They did not do so, which suggests they did not feel compelled to do so.
Speaking of the apparent lack of clarification, there are many other cases of unspecified concepts and techniques. For example, "ascendant" was meant as a specific sign, a specific degree, or a specific house (to name the most obvious cases), depending on context but never formally defined. Furthermore, if there were no other "house systems" (the "equal system" being only a specifically degree-based subset of the whole-sign system), then why should one have bothered with definitions?
Michael Sternbach wrote:Dorotheus is saying here that a planet within a 15 degrees orb from the Ascendent (understood as an angle) should be counted to it even if it is in an adjacent sign. So, in effect, he goes on to use 'Ascendent' in the other sense the ancients sometimes apply that term, i.e., synonymously with the first place/house. Which in this case indeed extends in both directions from the angle, covering 30 degrees in total.
I am sorry to say, but I think your interpretation is wrong and so are the implications you assume. But let me revisit the relevant passage (Ar. Dor. 1.7.7, pp. 68-69 Dykes = p. 165 Pingree). It is found in a chapter devoted to the question of upbringing, and the places (houses) promising successful upbringing are listed. One of these places is the ascendant (the first house), and here you find a specific instruction:
"And if you found 15° between a planet and the Ascendant, even if it was in the second sign from the Ascendant, then
take its power into account just as though its placement is in the Ascendant (emphasis mine)." (Dykes translation)
"If you find a planet [such that there are] fifteen degrees between it and the ascendent, then, even if it is in the second sign from the ascendent,
reckon its power as if it were in the ascendent (emphasis mine)." (Pingree translation)
The highlighted clause in the Arabic (p. 8.13 Pingree) reads as
fa-ḥsib quwwatahu ka-mak??natihi fi ṭ-ṭ??liʿi, which, quite aptly translated by Dykes, clearly means something like "take its (i.e., of the planet being in the second house but within 15 degrees from the ascendant) power (i.e., for upbringing) into account (in the same way) as if it is positioned in the ascendant." In other words, a specific rule is introduced here, but the text by no means says that a planet located in this fashion
belongs to the ascendant (the first house), and to assume that the same fifteen-degree interval should be measured clockwise from the ascendant to yield a 30-degree "house" in no way follows from the text.

As I don't have those sources at hand, I would appreciate if you could provide some quotes.
Here you are:
Book of Aristotle (Dykes translation): "And so, the Lord of the triplicity [being found] from the first degree of the sign up to the fifteenth, wholly with the degrees of the arisings of the Sun, and it (sic!) in a pivot, blesses the one who is born with luckiness, furnishes with dignities, adds attendants, even underofficials and scribes, nor will he ever happen to be deprived of dominion or power."
Horoscope of Constantine VII (my translation): "And Dorotheus adds the following (factors to consider): since the first trigonal lord of the Sun, which is Venus, is found pivotal in the hour-watcher, on her own throne, within 15 portions from the hour-watcher, the native will have greatness of fortune, especially in the first age of his life."
