This formula is missing a factor, there should some variable that stops the chances from going over 90% , thats why the formula is always CLOSE but not exact.

The formula probably isn't missing anything; there's probably just code after it that says "if the chance is above 90%, it equals 90%", so that part isn't factored into the formula.

This is nice now I know I have 90% chance on a planet with 5500 total defence.. that's quite useful

Nice to know i have 90% on a planet with 1000 total def

+100.....nice deal thx

+1

excellent effort, nice to see theory crafters at play crunching the hard numbers for the benefit of our comunity. if only someone would figure the scanning chance formulae...

That one is gonna be hard now that we can't see percents.

How does Invasion Defense compare to normal defense? Is Invasion defense only taken into account during invasions, but not for attacking?

Yes.

Scan appears to require a bit over 16 scan per planet at 50% chance, but I am still working on it. It might not be that linear. 50% is when that notice appears that you need more scan to avoid wasting energy.

I think the scanning formula has a exponential factor in it ( a number to the power of somethin'), i don't care about the scanning formula, i'd rather find out the NPC occurance thing that reverus is doing

Edit

Deleted my previous thing i had posted here, and would like to say the formula is dead on for me, when i stop being an idiot and use the correct numbers anyway

Bloody good work commonwealth- i am impressed

thanks!

but i got 60% for my math test

So the true Invasion Formula is actually:

Let f(x) = your invasion percent chance

f(x) = ( Ship Attack + Ship Invasion Attack ) / 3 / (Planet Defense + Planet Invasion Defense) * 100

If f(x) > 90, then f(x) = 90


Really nice job commonwealth

tag.

you can fail on a 0 def, though, so it's probably

my_att/3/(planet_def+C)
where C is some small constant.

Looking at it now, the fail on a 0 def is necessary to avoid dividing by zero (which might create a black hole and kill us all)

Don't forget to add Planet Attack as well, Zap.

Not necessarily; it could be if(totalInvasionDefense == 0) chance = .9; basically saying if the planet has no protection they have the maximum chance.

That's possible too. Maybe there should be an artifact that raises your chance on 90% invasion success planets to 100%..
