Explanation
Billing and billable-unit estimates
Local ceilings prevent known over-budget submissions but do not administer an account.
Pangram 4 text estimation uses one unit per started 100-word block, with a minimum of one. Text plagiarism uses a fixed five-unit estimate. Combined text analysis sums both. Bulk sums item estimates and enforces Pangram's 1,000-unit request limit. Estimates are preflight controls, not account balance checks.
