A few observations about the location formula (from Jessica Sisk):

1. The location is usually introduced by EN + the dative of the city or village followed by the genitive of the nome or district. The most popular location for these documents is Krokodopolis of the Arsinoite nome. The pool of documents seems to center, on the whole, in the Faiyum region (Upper Egypt).

2. The location formula sometimes repeats itself within the body of the text. This may be standard, but we often do not have the full document, which would allow us to determine how formulaic the repetition is. Examples include P.Petr.2,16 which features the location at least 4 times, while P.Petr. 21 repeats it something like 8 times. I think this accounts for the fact that Perseus produces "duplicates" on the hit list for the formulas.

3. The formula varies in the degree of descriptiveness. A more elaborate example is P.Hamb.24, which gives a location as the city "Arsinoe on the promontory of the Themistous district of the Arsinoite nome."

4. There are other locations often embedded in the documents which don't necessarily follow the initial Ptolemaic formula.  I have included such examples in the list, namely P.Hib.90, P.Petr.2,16, P.Petr.2, 22, P.Petr.2, 25 and SB 14013.

5. You'll notice that I have not used regnal years, although the list is chronological. Also, in the initial Perseus list P.Petr.2 was placed in Year 14 (July 234-) but the text is actually from 238/7 (regnal year 10 or 11). There may be other dating issues like this one.
