A mistake to avoid
Exact bonus percentages and rank thresholds need release-build verification. A bonus is not a substitute for unmet needs.
What still needs live data
Exact numerical values, release-build menus and reproducible gameplay tests will be added only after verification.
Exact values and operating advice are added after testing against a recorded game build. Check the source date before relying on a number.
