The Great Virology Mystery

[Oak]

I've been trying to figure out all the great secrets of Virology, but I keep running into walls that don't make sense to me. Making healing viruses is simple enough, but I've been trying to make airborne diseases and bioweapons and they never turn out how I want. Could any experts of the system lend me their knowledge?

If you look at my attached file, I have made a necro virus. I have also attached my basic calculations. According to the wiki, this should spread by air, but for some reason is always ends up as contact. 

Here is the Virology Wiki Guide for reference, it has all the values and algorithms.

I've been trying to figure this out, but I'm not sure I can. This problem has ruined countless beard, hallucination, and combustion viruses.

The only way this is going to get solved is by code diving IMHO, if I get some time I'll look into it.

Mhm I remember that and another person has reported a similar problem. It might be related to the number of symptoms also influencing stats. I did not get time to properly code dive, but likely will later today.

The actual formula for the transmission is a bit wonky: (DM code)
clamp(2 ** (properties["transmittable"] - symptoms.len), BLOOD, AIRBORNE)

So written in numbers and more readable pseudo math:
between(2^(transmittable - num_symptoms), 4, 64)

So it seems the wiki is off by 1. 2^6 = 64 = AIRBORNE. 2^5 = general contact. 2^4 = hands contact. 2^3 = feet contact and below is just blood

I'll change it on the wiki page

God bless farie and his cocerning knowledge of viro.
