Even though the statistical average is 23-ish, the fact is you are more likely to get less than that. The reason the average is so high is because of the fact that if you DO pull off three or four rolls you will roll significantly higher (1.5 - 2.0 times two rolls, obviously) Notice the peak of the probability curve is MUCH lower than 23, actually almost half that! This does nothing for the fact that even with 100k iterations, the distribution curve is hellza flat.

    Also, notice my curve goes out to 100? That means it is including the small chances of 7+ successful non-double rolls, skewing the average far to the right.

    In any case, I'll be bringing the Tervigon for it's capability to capture objectives, not for potentially bringing out 20+ Termagants.
    Okay, you are right. I assumed a normal distribution and it ain't. The average remains the same (23 termagant) though. Median is 17 termagant. Frequency peak is somewhere between 10 to 15 termagant. Now, what I think is more helpful to say is that a tervigon will spawn between 11 to 31 termagant (50% of all cases).

    Cheers

    I don't want to sound like I am being contrary, but I would really have difficulty passing off this statement. While it is technically true (that is, integrating from 11-31 gives you roughly 50%) saying "You have a 50% chance of spawning between 11 and 31 termagants" implies you have an equal chance of both 11 and 31, which is clearly not the case. I only say that because most people assume a normal distribution, which this is not.

    I did run the simulation again, capping the spawn rate to 7 turns, but the numbers didn't change that much. The Weibull distribution is still skewed slightly to the right, but it is not as bad and definitely better than when I tried to fit a double gaussian.

    I think if anyone asks, an appropriate response would be:

    The statistical average of spawning Termagants is approximately 23 per game, but the peak probability is roughly 14 Termagants based on numerical analysis. The fact is that the variation is so large that you can not reasonably assume you will spawn any more than 16-18 Termagants per game, even though the average is much higher than that.
    The range of 16-18 Termagants is based on the back slope of what I assumed was the dominant gaussian.

    This thread is getting quite serious... That's cool with me.

    That's why I pointed out that the median is 17. Yes, you are more likely to have 11 termagants than 31.

    That being said, I think with both agree with each other. It's just a matter of how we expose the result. Lets settle this with a friendly hand shake shall we?

    Thanks for this. I was trying to figure out if I owned enough termagaunts to use a tervigon, without having to rely on a pool of casualties. With your help I have concluding that I just have enough to field a single tervigon as a troops choice, but I will need to acquire more gaunts to use 2.

    if you already have the programm, could you prolly make a run to show how the average changes if you give the tervigon less time to spawn?

    from an educated guess the numbers should not decline much if you only gave it 3-4 turns as the dominant factor is that it runs out but I'd like to know as I plan to use tervigons for objective grabbing mostly and therefore staying a few turns in save reserve is the plan

    If you cap the spawns to three turns, the average does change a bit, but it is all from the far right edge of the graph (it looks like oyu just lobbed it off at the 50-ish point. I would expect the same number as without.

    Which is why i usually won't be pooping them out until turn three anyways.

    Hmmm, your math indicates that you could spawn a negative amount of termagaunts.
