Ok I found this topic so interesting I discussed it with my playgroup, the result was a really nice visualization of whats going on. With the risk of busting people’s balls I wanted to share it, I believe it will at the very least make it easier to find our point of disagreement (believe me, I have no problem being proven wrong but I really want to understand why I am wrong cause this bad boy has been bugging me)
Check this illustration
The green color shows the cards a corp will see in a game.
X is the potential position of a single Jackson card.
We know that the probabilities of a corp drawing a card in a netrunner game are fixed (for example 1 in 49 for a single copy) and thus we have a closed system where these odds are preserved. If milling also followed a specific behaviour or “law” (for example in the illustration Noise mills 1 card every game) you would get the exact same result, because milling gives you 1 additional chance to look at a card.
The problem is milling doesnt follow a pattern. Milling doesnt have a fixed probability of happening. You might draw a virus, you might play it or you may not, you might lose it to net damage, or you might simply never draw it. In a set of 5 games probabilities say you will see your single Jackson Howard 1 time in each position. But for milling there is simply no rule, what happens in the first 5 games may not happen in the next 5, and even if you keep stretching it to infinity you wont see a pattern.
The whole mill factor is an independent system of probabilities, totally chaotic and following no pattern. When you throw that at a closed system (a deck with 1 Jackson) you will mess up that deck’s odds.
I believe that it all comes down to that, If there is something in this last detail I am missing, at least I am confident that it is now easy for someone to point any error out. Or help them see the point im supporting which is the probabilities of milling and card positions in a deck are two independent things, and since one of them follows no pattern it will never show a fixed probability.
EDITS:
Things i should have already included: the order of the games is compltetely irrelevant, they are for visual convenience, whats important is that probability says in 5 games you will see Jackson at 5 different positions, you can read the table anyway you want.
Also, do not assume that the fact that I used 0 and 1 scenario means the chance of them happening is 50-50. It is NOT. You have a lot of random variables (draw, not draw, damage) but you also have human choice. And there is no pattern in that, so we cant say that stretched to infinity we would end up with 50-50 (which would mean you would have an equal number of games were the corp saw more Jackson and ones where it didnt see him, because yes, I could have created the tables in way that they would have caused more Jackson Howards to be seen than the average 9).
