Presumably, you mean Valens 2.37.20-21 (p. 105.35-106.4 Pingree) but I haven't found a reference to degree-based calculation there. However, another passage in Book IX may be instructive, and although it's not attributed to Petosiris or Nechepso, a reference to them closely follows, and its cryptic nature makes likely that it comes from their books.
I'll also quote the Greek text (Valens 9.2.5, p. 319.7-10 Pingree) because it's really tricky:
π??ὸς δὲ τοὺς τῆς ζωῆς χ??όνους συγκ??ινόμενοι οἱ δ??ο κλῆ??οι, π??ός τε τὸν Ἥλιον καὶ τὴν Σελήνην καὶ τὴν μοι??ικὴν α???τῶν ἀπό????οιαν, π??ός τε τὸν ὡ??οσκόπον καὶ τὸν πλανητικὸν σκοπὸν καὶ τὴν μοῖ??αν π??οδηλώσουσι καὶ τοὺς βιωσίμους χ??όνους ???κ τοῦ διαστήματος.
Mark Riley translated it in this way:
"With reference to lifespans: the two Lots, when calculated with reference to the sun and moon and to their distance <from> in degrees, and with reference to the Ascendant, the planet under consideration, and its degree-position, will make clear the span of life."
Riley translates πλανητικὸς σκοπός as "the planet under consideration", which is rather puzzling, and omits some phrases to make the text more understandable. Stephan Heilen also translated the passage (
Hadriani genitura, p. 1174), to German:
"Wenn man die zwei Lose bezüglich der Lebenszeiten (von Nativen) miteinander kombiniert, sowohl bezüglich der Sonne als auch des Mondes und ihrer gradgenauen Distanz, bezüglich des Aszendenten als auch des Ziels ihrer (der Luminare) Wanderung (d.h. des Deszendenten), werden sie sowohl das (individuelle) Schicksal als auch die Lebenszeiten aus dem Abstand offenbaren."
Here this enigmatic πλανητικὸς σκοπός is translated as the destination of the wandering, possibly of the lights, which he interprets as the descendant. I disagree and would use a different interpunction of the text to make it wholly comprehensible. (Note that the interpunction is the privilege of the editor; the manuscripts aren't reliable in this respect.)
π??ὸς δὲ τοὺς τῆς ζωῆς χ??όνους, συγκ??ινόμενοι οἱ δ??ο κλῆ??οι π??ός τε τὸν Ἥλιον καὶ τὴν Σελήνην καὶ τὴν μοι??ικὴν α???τῶν ἀπό????οιαν, π??ός τε τὸν ὡ??οσκόπον, καὶ τὸν πλανητικὸν σκοπὸν καὶ τὴν μοῖ??αν π??οδηλώσουσι καὶ τοὺς βιωσίμους χ??όνους ???κ τοῦ διαστήματος.
My translation (which is necessarily imperfect, though tries to grasp the important details) is this:
"Regarding the length of life, the two lots, as they combine in reference to the sun and the moon and their distance by portion as well as in reference to the hour-watcher, will reveal from their distance the end of the (native's) wandering and the destiny and the time of living."
The trickiness of the passages comes from the frequent usage of ambiguous expressions. The most annoying one is certainly this πλανητικὸς σκοπός, which is a combination an adjective originating from the noun πλανήτης (literally: "wanderer", but also meaning "wandering star", that is, "planet") and a noun, which, originating from the verb σκοπέω "inspect" or "watch", may mean the person, the act and the aim of watching both literally and metaphorically.
For our subject, however, the phrase μοι??ικὴ ἀπό????οια (distance by portion) matters: this consists of the adjective μοι??ικός, which, stemming from μοῖ??α, meaning both "fate" and "degree", could also mean "fatal", and the noun ἀπό????οια, whose literal meaning is "emanation" or "effluence", but astrologically "separation" is meant in general. Now, even if Nechepso, Petosiris, or whoever of poetical inclination composed this text, allowed it to be understood as referring to a degree-based calculation, no matter it could also be translated as "their distance decreed by fate".
