Over 50% SDI and I only stop 3 of 9 missiles?!

50% SDI doesn't mean you'll stop half the missiles, it just means that you have a 50% chance of stopping each individual missile.
33% stopped isn't all that bad, really :P

There are 84 different ways that with 9 missiles, 3 would get shot down.

With exactly 50% SDI, there would be a 16.4% chance that if 9 missiles were shot at you, that you would only shoot down 3 of them (84/2^9 = 84/512). Seriously, if you're going to complain about SDI not working, complaining about something that had a 16.4% chance of happening is quite foolish.

If you have 50% SDI, there's a 1.8% chance that you only stop 1 of the 9 missiles. Even then, its not an unreasonable result of random variation.

LATC, by your math, you should have shot down 4.5 missiles

"A chemical missile from (#666) I break for Tran (HAN) was partially intercepted by your missile defense system, 1234.5 civilians were killed and 33.5 buildings were destroyed!"

Send more missiles for more test data! :D

you're telling me that the R in RNG stands for random?


NO WAIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII!!!

If you want to talk about something being broken, try talking about how a country with under 1/4th the SPAL and under 1/4th the total spy power can get a successful bioterrorism on another country in just 2 attempts, and kill over half of that country's civilians with that one bioterrorism spy op on a country with what should have been more than sufficient protection against spy ops.

That's one of the many many examples of the game being broken.

That was the country, which was apparently still not adequately protected against harmful spy ops from countries with far inferior SPAL.

Not everyone is a math wiz. Give the guy a break :P

I personally think SDI is broken to.

I had over 75% SDI and Sof got over half their missiles thru on me before they killed me.

I think that SDI should be changed, so that if you don't have enough SDI, your country attracts missiles being launched towards other countries.


"I AM AWESOME (#46) launched a nuclear missile at Suspicious Multi Number 2 (#849). Unfortunately, your SDI defense systems deflected the missile towards your country, causing it to detonate over your territory! You lost: blah blah blah."

we are so sooo soooooo pathetic . . .

sdi has been same since dawn of time.

The random number generator was tested extensively by me and is accurate to the 99.9th confidence level which for purposes of this game is more than good enough, in fact is overkill. Translation: when it says something has a 50% chance of happening, the real probability per the RNG is somewhere between 49.98% and 50.02% 99.5 times out of 100. Based on what the algorithm actually is, it's probably better than what I tested it at. In fact in the whole history of the server until we are all dead the pseudo sequence won't generate a duplicate either assuming the seed hasn't been reset.

if you have 75% SDI and you stop 3 missiles out of 9, that would be unlucky but not sufficient evidence that the rng is broken.

On mehul's server the rng was actually broken:P

Or . . . was it?

heh, interpreted as broken maybe :P

broken from players viewpoint, working as supposed to from mehul's viewpoint.

I retract my statement, stopped 7 of 9 after buying back up to 55%.. now it's broken the other way =P

"let the bell curve, be unbroken, by and by lord by and by"

At one point we had a full reset's worth of missile results made public for anyone to wanted to crunch the numbers. Nothing was broken...

This is just an example of negativity bias.

Guy with no clue.

9 is too small a sample size to accurately assess a proportion anyway.
I used a sample of 10,000 random numbers :P

50% of the first 9 - 4.5
55% of the second 9 - 4.95

Total - 9.45

You block 3 out of 9
You block 7 out of 9

Total - 10

Sounds about right

have you guys ever looked at spy success rates? ive been griefed by people with roughly equivalent but slightly worse SPAL vs mine and they blow up thousands of buildings daily

SPAL probably suffers more from diminishing returns than any other function of the game. A good SPAL is good, but a great SPAL is meh.
