KBC-01G: Variable Data Location Optimization (Affected Lines: L51)

150

KBC-02G: Inefficient Variable Declaration (Affected Lines: L72)

Saves 3 slots from being loaded, that's 2.1k * 3 6.3k

KIB-01G: Unused Private Contract Member (Affected Lines: L40)

Valid QA but no meaningful savings

KIB-02G: Redundant External Self Calls (Affected Lines: L142, L170, L276, L281)

100 per instance = 400

MAR-01G: Improperly Empty Chainlink Format Variable (Affected Lines: L86)

Not a savings finding, but definitely a good suggestion

Would guesstimate the rest of the optimizations at around 50 / 100 gas each

Above 7k saved

Great report that is customized to the contest!
