Calculation method
Request count by supplied approval tier
Assign each amount to the first inclusive ceiling it meets; the final tier must be unbounded.
Review workload by tier (minutes)
Tier count×supplied minutes per request.
Requested cash exposure by tier ($)
Sum requested amounts assigned to each tier, without treating them as approved credits.
Review-minute shortage by tier
max(0,tier workload−reviewers×available minutes).
Total review workload (minutes)
Sum tier workloads; an assignment is not a real approval.
