Configurable Core Miner Returns

A Factorio mod that allows you to configure the diminishing returns rate for Space Exploration core miners.

Features

• Adjustable diminishing returns rate (0-100%)
• Default 10% diminishing returns per additional miner
  

How It Works

Each core miner after the first contributes slightly less than the previous one, based on the configured rate.

With the default 10% setting:

| Miners | Marginal Efficiency | Average Efficiency |
|--------|--------------------|--------------------|
| 1 | 100% | 100% |
| 2 | 90% | 95% |
| 3 | 81% | 90.3% |
| 4 | 72.9% | 85.9% |
| 5 | 65.6% | 81.9% |
| 10 | 38.7% | 65.1% |
| 20 | 13.5% | 47.2% |

• Marginal Efficiency: The efficiency of the last miner placed
• Average Efficiency: The displayed per-miner yield (total output ÷ miner count)
  

Settings

| Setting | Type | Default | Range |
|---------|------|---------|-------|
| Diminishing rate per miner | Map | 10% | 0-100% |

Set to 0% for no diminishing returns (all miners at full efficiency).

Configurable at any time via Map Settings - no restart required.
