ATO block is not step-up mix
ATO blocks ÷ auth attempts make block %. Type both.
Pair: ATO-block share on Chargebacks. Mix: step-up vs block mix. Overturn: auto-block overturn rate.
What you type
ATO blocks — Forter account-takeover blocks in the window.
Auth attempts — Auth attempts in that same Forter window.
Block % = ATO blocks ÷ auth attempts × 100. Tune ATO rules when block % is fat — do not invent a block chip.
What not to do
Do not invent block %. Do not mix step-up abandons into ATO blocks. Do not treat Sift auto-block overturns as Forter ATO share. Do not average every MID when one owns the hole.
