In Costa Adeje the assistants tell the neighbourhoods apart
- 562
- distinct venue names that came out over the whole run
- 460
- of those names, how many come out at a single point
Read the second row against the first: 460 names out of 562, about four in five, come out at a single point.
Source 134 completed readings out of 135 attempted, made by us on 12 September 2026: 9 points in Costa Adeje, 5 questions, 3 assistants.
We asked the same question from 9 different points in Costa Adeje, and got 562 venue names back. Of those names 460, 82% of them, come out at a single point: about four names in five change as soon as the neighbourhood does.
There were 5 questions and they never changed. Only the point written inside the sentence changed, first El Duque, then Playa del Duque, then La Caleta, and so on for all 9, picked by hand before starting. 135 readings in all, of which 134 completed and 1 was lost to a dropped connection.
The two closest points give two different lists
El Duque and Playa del Duque are the two closest points on the grid: the coordinates we declared are about 300 metres apart, under a ten minute walk along the same beach.
El Duque gave 94 names and Playa del Duque 88, but they share only 31, about one in three.
The names that come out at every point are 5, fewer than one in a hundred. Those are the venues that show up whatever neighbourhood you name.
One assistant of three produced no names, and that one is on us
There are 15 pairs of question and assistant. 10 of them, two in three, produced at least one name, and all 10 change names from one point to the next.
The other 5 belong to one assistant, ChatGPT, which answered every time at length and with plenty of venues. It does not use bold, though, and our extractor reads exactly that. Those 5 pairs come out as "no change", but there we are not measuring the assistant: we are measuring a tool of ours that cannot see. That is why the figure of this piece is 10 of 10 and not 10 of 15.
Of the 16 venues we listed before reading anything, 13 come out at least at one point: all but three.
What this does not say
This is one run, on one day, on one area and one category. Running the same 135 readings tomorrow some of the names would change, because these assistants do not repeat themselves; how many, we do not know, and this run was not built to find out. We picked the 9 points ourselves, and another grid would give other numbers. The 82% holds for these 134 readings, not for Costa Adeje at large.
