OK, I have a planet generated.
Homeworld 75555
Now I see the Albion planet in your example.
Earth - Ring 3 Segment 9 Planetary Data 557553P
There is an extra number and a P on it. I only found 5 stats, not six. I assume the P means planet?
I am still looking at Pregame setup.
The last number is the following:
The Planetary Surface Area refers to the percentage of the planets surface that is usable by the colonizing power and can range from 0 to 9 with a T meaning 100 percent is usable.
On a species Homeworld it is the difference between it and water coverage on the planet. for a colony it will be modified by the other stats as well. Usually the Colonization cost is a pretty good indicator of how much surface area is usable. the higher it is, the less the colonizing species can use.
For example, Earth has a 7 in its water coverage so the surface area is 3.
Your planet would have a surface area number of 5.
Yes, the P stands for Planetary Data.
