One of the things your analysis assumes is the communication is being done by radio/laser communication over interstellar distances. This is the assumption in the original article you cited.

The Cymbeline for example don't have the technology to achieve that. They should be removed from the map, or marked with a different color. This is true of every sophont with a TL of 5 or less. 

The harder question to answer is what would the TL of the races contacted by the Vilani be if they were not contacted.

There's no real information that can be easily extracted from the map. The closest to Terra are the Chips in the Cymbeline system (6.08 parsec), then the Vegans in Muan Gwi (10.53). Cymbeline has a real-world star associated with it, L399-68 ( http://simbad.u-strasbg.fr/simbad/sim-id?Ident=L399-68&NbIdent=1&Radius=2&Radius.unit=arcmin&submit=submit+id ), but that is the only one.

Gee, that's a lot of minor races.

How many of them are human, I wonder?

Of course, The Ancients probably 'discovered' all of them & who knows what they did, or didn't do to/with them.

If you use the minor race data from Travellermap, which I have drawn here as small blue circles: https://i.imgur.com/qm4MWrv.png

I would say that Traveller is far more than Generous. The mean distance between any two of those civilizations is 5.88 parsec, and the furthest any of them is from another minor civilization is 25.16 parsec. Some of them are so inconsequential that they are named nothing more than "minor":

The english in the article is not so good. The research appears to be in preprint stages and originates from the University of Nottingham.

Pessimistic view: 4 civilizations actively communicating.
Average view: 35 civilizations actively communicating.
Generous view: 211 civilizations actively communicating.
Mean Separation: 17K light years (out of our ability to detect).
The Generous view seems to lead to a seperation of a few hundred light years.
Assumptions obviously made, some changes made to the Drake Equation (or at least particular choices of inputs).

Hopefully this research will reach a printable stage and we can see the actual study/article.

If the Generous view is taken, and distances between communicating civilizations are a few hundred light years, that would mean 100+ Jump-1s (ObTrav). I'm not sure the difference between Vland and Terra or Vland and Zhodane, etc, but they might fall within a few hundred to a thousand light years separation.

The number of sophonts in the TU can't really be compared to these metrics simply because many may not have been communicating when contacted. There may be many more of those.

Of course, if you went with the average case, 35 communicating civilizations around the galaxy, 17K ly separation, that's over 4K Jump-1s between.

So the OTU, if these numbers have any validity (entirely questionable!), would need to fall under the Generous assumption.

PS - I look at these things as interesting and kinda fun, like gambling or astrology... I feel like the assumptions involved make the outcomes as valid as casting carved bones with runes on them to help make decisions.
