One hour walk

Odyssey Book 17 line 76-80 Barry B Powell

An hour walk ring

... he led the much-suffering stranger Theoklymenos toward the house. And when they came to the busy household.... ....and went into the well-polished bathtubs and bathed... ...The revered housewife brought in bread and placed it down before them, and many meats too.

After they took their baths, bread and meat was served, so it must have been lunch time, estimated at midday. That will be at 12:20 December 19th. Let's say that bathing took an hour, the whole trip to the assembly and back (8:25-11:20) took about 3:00 hours.

Palace

The suitors took a long time for having the indecisive gathering, Let's see what time it took for Telemachos to get back and forth to the place of assembly.

Pyrgi

The briefing of the friends took 30 minutes (9:10-9:40) and when the time needed to get permission for Theoklymenos took about 45 minutes (9:40-10:25), the place of assembly is indeed between 45 and 60 minute stroll from the palace.

Found! the place of assembly!
A good moment to summarize our findings

So, this fits the green segment very well. The routes of the heralds fit Pyrgi very well. The route Theoklymenos and Peiraios walked fit both the segment and Pyrgi fit very well too. And Pyrgi is like Alkinoös' Scheria close to the harbour. So, Pyrgi must have been the place of assembly.
