Description:

This mod has two main objectives:
To define a game environment mimicking real-life farming.
To enable players to individualize the game using a simple editor.

Version 1.0.0.3
1. RealNumbersStoneScaling.lua: Added a script to scale the size of field stones.
In the downloaded version, the size scaling parameter is set to one. You need to pick up all existing field stones before changing the stone size scaling factor. If you downscale the size, the stone picker will not recognize the stones with the original size.

In this case you have two options:
Cultivate the field again. This will delete the old stones and spawn new ones.
Set the stone scaling parameter back to its previous value and pick up the old stones.

I have tried setting the scaling parameter to 1/2. This gives smaller but visible stones. For very small scaling factors, the stones become invisible. If you make the stone size very small, you might as well turn off the stone system.
The equipment wear factor it set to scale as the square of the stone size scaling. If the stone size is scaled by 1/2, the wear factor on equipment is scaled by 1/4. If you increase the stone size by 1.41, the wear factor doubles.
The stone yield while stone picking can also be scaled. However, I have not been able to adjust the density of stone spawning.
2. RealNumbersStorePrices.lua: Added an opportunity to set dailyUpkeep as a percentage of the retail price. Unique scaling parameters have been defined for a range of item categories.

Version 1.0.0.2
Added a script RealNumbersTreeLogPrices.lua to adjust prices of the 19 wood types in the game.
The mod user may adjust the price of milled wood to desired price levels. The mod then calculates the sales price of logs. A table is printed to the log file.
To adjust the helper fee, please use the mod AIcost by HappyLooser.

Version 1.0.0.1
Fixed price scaling when buying multiple bales, bigbags and bigbag pallets.

Version 1.0.0.0
Consider this a beta version. Testing has been very sparse.
Play on economy-level HARD!!

This mod is very downscaled compared to the original mod for FS19. The FS22 version includes the following scripts:
RealNumbersFieldPrices.lua: (press lAlt-rf to get a list of field area and other information)
-       Adjusted prices of farmland
-       Defines a fraction of the farmlands as leaseable at a reduced cost (can be turned off)

RealNumbersFillTypes.lua:
-       Adjusted pricePerLiter (only fillTypes, not buildings or equipment)

RealNumbersFruitTypes.lua
-       Adjustable yield, windrow yield and seedUsage (default is no scale)

RealNumbersStorePrices.lua:
-       Adjustable prices for bales, bigbags, bigbagpallets and pallets

RealNumbersLeasing.lua:
-       Adjustable leasing cost for equipment (default: flat daily fraction of trade value)

RealNumberContractRewards.lua:
-       Adjusted rewards for missions

RealNumbersSellingStations.lua
-       Reduced price variation between sellPoints

Still to do: reduce helper wages.
Each script is independent. All scripts, except RealNumbersFieldPrices.lua, can be commented out in modDesc.xml.
There is only one universal version of the mod. Mod users in different parts of the world may need to adjust the price scaling inside each script to fit price levels in their part of the world.
In the FS19 version, a unique set of parameter values were defined for each item. I do not have the time to repeat this detailed approach in FS22. In the FS22 version, items are scaled in large groups. E.g., all fillTypes are scaled by the same number.
This mod has not been written for Multiplayer mode. Nor has it been tested in Multiplayer mode.
