NMI address-match miss is not Solidgate AVS fail
Divide address-match misses by auth attempts on one NMI auth export. That ratio is address-miss %.
Pair: AVS-fail share on Payments. Solidgate twin: AVS fail. Trade twin: AVS/CVV tradeoff.
What you type
AVS fails — NMI auth attempts that failed address match in the export.
Auth attempts — Auth attempts in that same NMI auth export.
Address-miss % = address-match misses ÷ auth attempts × 100. Fat address-miss % usually means AVS rule heat or bad bill-to — retune that rule; never invent an address-miss chip.
What not to do
Skip inventing address-miss %. Skip dumping a Solidgate AVS file into NMI fields. Skip folding CVV fails into address-match misses. Skip blending MIDs when one seat owns the miss pile.
