Expansions: BGS Guide Best Current Thinking

Jane, we've had expansions that have skipped and it's either down to expanding population being too small for a large population or a large population ignoring a small population and going for a large population. We have also had a double expansion where a medium population expanded to 2 small populations.

I'd also add that some systems may be reserved and that's why they are missed, but missing so many? That is weird.

Just had an expansion of 31.56 without an investment.

The previous expansion was 34.27 also without an investment, though my assumption then was it used an unused investment that was followed by an alternative expansion out of a different system.


There are 15 or so closer systems with at least space and no retreats to consider.

Baffled
Whats the difference in coordinates of the systems? i did a check on a similar expansion we had a while back and it turned out all the closer systems skipped were outside of a 40ly cube centred on the expanding system, we skipped 6 seemingly closer systems. The system we expanded to was inside the 40ly cube

Edit: Pretty confident about the 40ly cube! I will bet 10 bgs transactions for your faction that all the available systems you skipped are outside the cube and the one you expanded to is inside

difference is 18.0625 / 17.875 / 17.75, that fits if you use a 40ly cube instead of a 20ly radius sphere for the expansion

check the others, if one of the deltas is more the 20 then its outside the cube

that really should only be reachable with investment.
It works if expansion is in a cube and not a sphere, i checked the first 3 closer systems available last night and they are all outside the cube.
I will contact you tonight when i get back from work for the details on all the other systems you skipped, i want to check them too!

what is weird about this is that this system had a space available well always. We've had investment required from the same expansion location previously.

here's mine

Ix Chodharr expanded to Arine 29.36Ly away and skipped 5 closer systems

coordinate deltas for skipped systems:

Hip 2293 21.74Ly 20.34375/4.28125/6.375
Col 285 Sector JJ-E b13-4 26.25Ly 0.34375/10.96875/23.84375
Masai 26.63Ly 24.40625/1.03125/10.59375
Aymarahuara 27.96Ly 11.8125/12.3125/22.15625
31 Cephei 28.13Ly 4.0625/10.09375/25.9375

coordinate deltas for Arine 29.36Ly 19.625/11.03125/18.84375

all skipped systems are outside cube and arine is inside

case is looking pretty good for a 40ly cube and explains a lot of the 20ly+ expansions seen over the years!
anyone else got some good data on a expansion that skipped closer systems?

we do still have the question of why this wasn't expanded to previously, since its always been open, and there has been an investment funded expansion needed from the same location.....

So percentage to trigger expansion must round up. We recently had and expansion trigger without technically hitting 75% (although it was close ... 74.7%). Not sure if this is known so I figured I’d share.

Are you sure, wouldn't an expansion after a investment have taken you to the system 20.72ly away?

Yes I'm sure - that's why I flagged it.

Our sequence was Investment. system 1 .... expansion from a different system.... expansion from the 1st system to 34 LY ..... expansion from 1st system to 31 LY.

There have only been 3 factions in the most recent expnansion target since 2016

Ah i see you mentioned that already i misunderstood, also strange you expanded to further system first!
 
Interesting info. I've got nothing to add since the last expansion just skipped over an Invasion thanks to a recovering war on that day.
Only odd bit is it jumped 20.98 ly for the destination, but that cube thought has me wondering some on it. Sometime I'll need to check it more detailed.
