On the other hand, size codes > A aren't in use in the T5SS data. I'd nominate X=Culture-style Orbital (no examples in OTU?), Y = Ringworld, Z = Dyson Sphere (e.g. Sphere/Nooq 3201)
Diaspora... Lots of TL changes there, and some others as well, on purpose. I'd use travellermap.com's data for 1105, but you can use whatever you'd prefer for your campaigns.
T5 Core Rules p.431:
W Worlds. The number of worlds in the system = Main-World + Belts + Gas Giants + Stars + 2D. This number does not include Worldlets and Satellites (other than the Mainworld if it is a Satellite).
Compare the Terra System, which is listed with 10 worlds (Sol*, Mercury, Venus, Earth, Mars, Mainbelt, Jupiter, Saturn, Uranus, and Neptune)
See that this changes coreward Diaspora HT political balance and situation quite a lot. Perhaps not important fot T5, but I'm mostly a MT man...
Per http://www.travellerrpg.com/CotI/Discuss/showpost.php?p=468717&postcount=305 it looks like including the Stars count is inconsistent in the T5 Core Rules.
So many ways to count the Terra system. Classic Traveller probably counts: Mercury, Venus, Terra, Mars, Main Belt, Jupiter, Saturn, Uranus, Neptune, Pluto = 10
Nowadays, you could replace Pluto with Kuiper (ice) Belt and keep the count at 10. Add Sol to bump it to 11. Or drop Sol and drop the ice belt and the count goes to 9. Or count Sol and the ice belt and add the known dwarfs (Ceres, Pluto, Haumea, Makemake, Eris) and get 15. But it'll probably be up to at least 20 by the time T6 rolls around.
Personally, I'd go with: Mercury, Venus, Terra, Mars, Main Belt, Jupiter, Saturn, Uranus, Neptune, Kuiper Belt = 10... which is what I thought the 10 in the T5SS data was referring to, before this thread.

The Tech level of Yori is said to be 10 (A).
In The Spinward Marches1, The Kinunir, Twilight's Peak, Secret of the Ancients1, The Traveller Book1, and the Fifth Frontier War boardgame, Yori's TL is 13 (D).
In The Spinward Marches Campaign, Regency Sourcebook, and MgT:The Spinward Marches, Yori's TL is 10.
In these three the accompanying notes include the sentence "...the highest tech level is D, at Efate, Uakye, Pixie, Boughene, and Yori."
The TL should either be changed to back 13 or the aforementioned books and boardgame errata'ed.
How do you calculate X-Boat routes?
