Proximity Effect on Cohort Files

[Eusebio Ptolomeu 24]

I've been poking around with iLiive Reader, and exploring the SimCity1.dat file, I came about some groups of "proximity effect" functions in elements at Cohort->General->Developer (use the navigator function for help). For example, in the Residential $ group, we have "R$ Proximity Effect", "R$$ Proximity Effect", etc. It defines how much proximity to a certain developer type affect desirability. When we analyze each function, it comes in pairs of numbers; I think each element in a pair represents the distance of said developer type and how much this distance affects desirability, respectively. I would like to play around with these numbers, but would like to have some ideas in mind, assuming my theory about the behaviour of the numbers is correct:
1- How exaclty does the distance number work? I see number such as 0, 120, all the way up to 255. Do these numbers represent single tiles, as in, 128 tiles of distance? Or they represent distance differently?
2- From what I see, it looks like the largest impact in desirability seems to be +/- 5. Is "5" a number big enough to have a noticeable effect in the desirability simulation? If desirability ranges from, say, 0 to 100, then "5" is quite negligible. What is the usual range for desirabilty in the game, so we can choose better values here?
3- Does these functions actually do anything in the game?Or is it more of a developer oversight, present but having no impact on the simulation?

It appears those values are used by the game as part of the growable lot system

Ingred.ini describes those properties as using a General Response Curve, but I don't know the exact format of the properties.

I'll play around with them and see what happens. In general, a building giving a desirability boost of 20 is too much or too little, in the game? I would like to increase the impact of desirability of this functions somewhat, but not to the point of nullifying every other desirability boosts a mayor could give; I'll check the boost value of small parks and take that into consideration.

The reason I asked if this function has any effect whatsoever is that, personally, it wasn't hard at all for me to see diferent wealth-types so close to each others, almost as much as if this function plays no actual role in the simulation; but then again, it could be the simple fact of the effect being too negligible to be noticieable.

Sadly the SC4D wiki is temporarily down, but the Exemplar properties page is usually what I would refer to. The distance is radius of tiles. 255 tiles is essentially the size of the large city. Generally, the numeric pairs are (effect strength, tile radius), in that order.

+20 doesn't seem wild. If you consult the Prima Guide, specifically chapter 10, +20 would seem to be on the low end of what most landmarks provide.

I decided to attempt some tests. I used the "Large City Tutorial" in Maxisland as a testing ground, made sure to clean my plugin folder before, to be certain no other mod is interfering with it. I decided to multiply the power of said effect 10 times, so where R$$$ originally had an effect of -5, I changed to -50, etc. I only changed the cohorts in General->Developer towards each residential wealth level, and only the proximity effect stuff. I didn't see much of an impact in the desirability map, however... maybe I did something wrong on the creation of the plugin?  I am attaching the dat file in this post in case anyone wants to have a closer look.

Quick new update
I decided to increase even more the power of the effect. Now I multiplied 20 times; funny enough, this makes the whole "Large City Tutorial" become entirely red in desirability... even for R$, which is weird, because I set them to ignore proximity to other R$ lots. I am attaching this update file here; I find it odd that the R$ desirability was so affected in this city, since there were no R$$$ to cause this downgrade, even if I increased the power of the effect so much.
