## About The Pull Request What it says on the tin. Cargo now has new math for market elasticity, each parameter and what it does is explained below **1. Refactor** 1. **k_elasticity**: This is the elasticity as before applied on all exports except now this is a floating-point value that swings from `0->1` instead of 10e-10 like is the current case. This in laymen terms is the percentile of an items actual cost that is sold on cargo [0 means you get no credits, 0.5 means you get 50% of the items cost, 1 means you get 100% of the items cost]. Whenever an item is sold on cargo this value decreases by an amount that is determined by the next variable 2. **k_hit_percentile(default 5%)**: This is the value by which an export `k_elasticity` decreases whenever an export is successful for every unit of an item sold. The real formulae by which the exports elasticity decreases is dependent on the total amount sold and is as follows <pre>k_elasticity -= amount sold (1 for most cases except stacks) * k_hit_percentile</pre> So subsequent exports yield lesser profits cause the elasticity decreases. Now the rate at which the elasticity recovers is as follows 3. **k_recovery_time(default 10 minutes)**: This is the time (minimum unit should be seconds) it takes for the elasticity to rebound back to 100% after it has reached full 0 but recovery process starts immediately if it decreases at any point. So if elasticity becomes say 50% it means it would take 5 minutes to reach 100% again **2. Some Balance changes** 1. Profits earned from exporting gas is linear per mole sold so the more gas you put in the more profits you get HOWEVER the max number of credits you can make per canister is 15000 cr 2. Selling fish yields higher prices because it's no longer subject to the old elasticity formula 3. Selling 50 sheets of anything will decrease future sale price by 10% and will take 8 minutes to rebound back to 100% if it reaches 0 **3. Improvements:** - `SSProcessing` subsystem no longer processes more than 180+ export datums from round start itself but now starts out empty. It instead processes only those exports whose elasticity has been impacted and later cancels it after elasticity has reached 100% so performance of this subsystem has been drastically improved - export datums now respect `abstract_type` meaning they won't be created and can be used as a skeleton body for subtypes. So datums like `datum/material` & `datum/material/market` are not created anymore but only their subtypes are so we save processing power & memory - Shaved of a lot of dead exports that went unused ## Changelog 🆑 balance: cargo exports now have different prices with applied elasticity code: Improved performance of export code qol: stock blocks can be recycled for materials & show up as stock blocks in order console sold items refactor: refactored cargo export code in whole.
