A worked distinction
A displayed 4% base component plus 12% reward component should be examined as two assumptions. If the reward token loses half its value while the same token quantity is distributed, its cash value is halved; the base component does not automatically change by the same amount.
What to verify in your own analysis
Inspect base, reward, historical-average and TVL fields separately. Do not convert a missing component to zero or assume rewards are sold and reinvested without cost.
Write down the market or protocol identifier, units, observation window and data source before comparing outputs. Keep unavailable values distinct from zero. Capture a baseline and change one assumption at a time so the resulting difference can be explained.
