PaperclipGo never hides its calculations behind a black-box server. You can verify every output directly against these formulas:

1. Average Cost per Coin   = Total_USD_Paid / Quantity_Owned
2. Current Position Value  = Quantity_Owned * Live_Price_USD
3. Unrealized P&L ($)      = Current_Position_Value - Total_USD_Paid
4. Unrealized Return (%)   = ((Current_Position_Value - Total_USD_Paid) / Total_USD_Paid) * 100
5. Scenario Value (Δ%)     = Current_Position_Value * (1 + (Scenario_Slider_Pct / 100))
6. Weekly DCA Compounding  = Σ [ (Prior_Balance + Weekly_Contribution) * (1 + (APR / 52)) ]
