Sift ATO reverse is not auto-block overturn
Score reversed ATO stops against ATO stops on one Sift ATO cut. That score is ATO-reverse %.
Pair: ATO-overturn share on Chargebacks. Volume twin: ATO-block. Broad twin: auto-block overturn.
What you type
Overturned ATO blocks — Sift ATO stops later reversed to allow / release in the cut.
ATO blocks — ATO stops raised in that same Sift ATO cut.
ATO-reverse % = overturned ATO blocks ÷ ATO blocks × 100. Fat ATO-reverse % usually means ATO rules are too hot — retune that path; never invent an ATO-reverse chip.
What not to do
Skip inventing ATO-reverse %. Skip dumping a Forter ATO file into Sift fields. Skip folding generic auto-block overturns into the ATO-only counts. Skip blending MIDs when one seat owns the reverse pile.

FAQ
- Is this Sift auto-block overturn rate?
- Sibling Sift door on all auto-blocks, not ATO-only. [Auto-block overturn](/manuals/sift-auto-block-overturn-rate) mixes every auto-block. Here you only score ATO stops later reversed to allow.
- Is this Sift ATO-block share?
- Sibling Sift volume cut. [ATO-block share](/manuals/sift-ato-block-share) is ATO stops ÷ auth attempts. This page is overturned ATO stops ÷ ATO stops.
- What ATO-reverse % should I invent?
- None. Pull overturned ATO blocks and ATO blocks from the same Sift ATO cut.
