2 mill not 50

Oh. k. sorry.

Send 56 BS. Its a 20% chance, I know that.

Also, 2 mil seems right:

A debris field containing 1.680.000 units of Metal and 336.000 units of Crystal has formed in orbit around the planet.
The probability of creating a moon is : 20 %

That came from the 56 BS moonshot.

How is the debris calculated? Structure points?
If debris is equal to 30 % of structure points:
2300 LF = 1,725,000 debris
56 BS = 1,008,000 debris
*no losses at the other side

With trade ratios at 3:1.5:0.5 , LF is the most cost effective way to create debris.
Even at 3.5:2:1 , LF is still cheaper.

That is if debris is equal to 30 % of structure points.

I believe it is based off of the Crystal/Metal used in the construction of the destroyed ships. Thats just a speculation, though.

its 60% of the metal crystal it costs to build

If debris is equal to 60% of metal + crystal cost.
2300 LF = 2,070,000 metal + 2,070,000 crystal
56 BS = 1,680,000 metal + 336,000 crystal

If Urweirdsaysi is correct then you will only be using 1,112 LF. That's 1,000,800 Metal + 1,000,800 Crystal.

LF would still be cheaper by only a small margin.
LF=3,336,000 BS=3,360,000

If you consider the trade rates(3.5:2:1)then the ratio will be like this: LF=10,920,000 ; BS=9,174,000

But there always seem to be a lack of crystal so maybe BS might also be a better option.
I did not check the different ships yet.

Something is really weird. If debris is equal to 60% of construction cost, then it should not matter which ship you build.
Theoretically to produce 2m of debris you need to spend 3.33m. The only factor would be the trade ratio.

i dont know why someone would use so many LF? i have no idea where that number comes from... another alternative is to use 223 LC which is easier on defences

Yeah... it is still not what I think it is.

Can anybody answer me if a moon is indeed created immediately after a battle (meaning, like some of you said, 50 BS+my planet=boom+moon, meaning that you have one shot of having a moon created at probability n%) or if it is depending on how long the debris field stays around (while you have the debris field around, you have a n% chance of getting a moon... somehow... and god knows how continuously would this probability be tested...)?

Thank you.

Best.
