The gap between these two numbers is the hidden verification tax — and it grows as AI accuracy drops or verification takes longer.

The real savings formula
−Manual effort (baseline)
100 units−AI gen overhead (~5% of baseline)
5 units−Verify all 100 cases (30% cost each)
30 units−Re-record 30 wrong cases (100% cost each)
30 units=Actual time saved
35 units (35%)
