Work one Chargebacks911 reason-code match desk. Count cases where the network reason code does not match the merchant fight reason. Divide by cases that desk scored. Multiply by 100 for C9 reason-code-mismatch %. Issuer-request reply desks and pack-build lanes never feed this match cut.

Pair: Reason-code mismatch share under Chargebacks. Reply twin: C9 issuer-request. Pre-arb twin: C9 pre-arb miss.
