ReStory Device Prices and Parts Costs, Explained
No component table is treated as a guarantee of revenue or an assembly route.
What each price means
Sell price and listed parts price come from community device infoboxes. They are separately stored so the site can display gaps without altering either source value.
How arithmetic is constrained
The site subtracts listed parts total from recorded sale price only where both numbers exist. It does not add tips, existing inventory, licence amortization or undocumented rewards.
Why some rows are conditional
Atari Lynx, Brick Game and Pokia Njoy have missing price fields. Patento BS has a stated total that conflicts with line-item arithmetic.
