Data and calculator policy
Every game-sensitive value needs a source, evidence tier, build, verification date and confidence. Manual inputs are never presented as verified game defaults.
Manual Mode
You supply the values and choose a consistent unit. We show the arithmetic and assumptions. Results describe your scenario; they are not an optimal strategy or a simulation of hidden mechanics.
Saved plans
Plans are stored in this browser’s local storage. They are not sent to a wiki account. Private browsing, clearing site data or changing devices can remove them. Export important plans before making changes.
Version changes
A changed recipe can affect several outputs. The patch-impact framework traces related records and dependent tools. Historical sources are prevented from silently becoming EA defaults.
