Wiki Query

[Carlobrand]

The Traveller Wiki sector information includes information about sector populations and gross product. However, it's not matching up to the canon materials: I show Spinward Marches with a lot more population, care of Spinward Marches Campaign, than what they show. Where are they getting that info?

 

[tjoneslo]

I'm getting the population information from the nroute.c program which generates the trade route PDFs attached. However, as part of the statistical analysis it doesn't interpret the population multiplier (from PBG) the way the rules (and everyone else) does. This re-interpretation ends up reducing the overall population (and GWP) of each sector, all of the Imperium, and indeed all of charted space by about 30%.

The reason for this is the original way the population multiplier was generated. (2D6-2) which puts a curve into the population multiplier that does not exist in real world population multipliers.

I'm currently in the process of updating the trade route generation program. This will used the more standard population multiplier interpretation. I'm waiting on the next update of the T5 Second Survey data.

But at least the resultant average (5) would be closer to real world multipliers than 1.[/quote]

Incidentally, it would have been easy to generate a number between 1 and 9 using two D6:

First die:
1-2 = 1
3-4 = 2
5-6 = 3

Second die:
1-2 = +0
3-4 = +3
5-6 = +6.

I'm currently in the process of updating the trade route generation program.

Are you going to account for long distance trade, that is, trade between worlds more than on jump apart?

Ah. Okay.

One more question: Zeycude. Has it been taking growth hormone? All the old stuff has it as a size 3, but the wiki and Traveller Map have it as a size 4. I know there's been some errata work on some of the worlds, but I hadn't heard of that including size. What other disparities should I look for?

One of the problems with the old world generation system was that it sometimes produced worlds that were too small to retain their atmospheres (unless some rather low-probability explanations were invoked). As I understand it, the current revision process includes having a look at such worlds and changing their size in a lot of cases.

Zeycude shouldn't be one of them, though. With a type 3 atmosphere (very thin) a size of 3 should be quite possible. Perhaps the change is a mistake?

Some TLs have also been adjusted, partly to put them back into line with the rules. Much of the stellar data has been updated. The population multiplier codes have been reprocessed.

Yes, absolutely. The updated process does the BTN calculation for every pair of the ~47,000 worlds of the 124 sectors in charted space, and using the distance chart in GT:FT, calculates the trade for every BTN 15+ route.

That will be interesting. I suspect (but don't know for sure) that some of the results will be quite different from those maps that only calculate world to neighboring world routes.

...and using the distance chart in GT:FT, calculates the trade for every BTN 15+ route.

Um... there isn't going to be any of those, is there? The BTN is limited to the largest of the two WTNs plus 5, so unless you have worlds with WTN 10...

Sorry. I doubled the WTNs and BTNs to avoid having to deal with floating point numbers. So BTN 7.5 or larger.

That will be interesting. I suspect (but don't know for sure) that some of the results will be quite different from those maps that only calculate world to neighboring world routes.

The differences are fairly dramatic.

Through the core of the Imperium there are enough moderate/high population worlds trading with each other it drives the trade routes to BTN 12 and in several places to BTN 13 even through none of the world pairs in the area would be over BTN 11.
