**Run date:** 2026-08-23

## Experience and arithmetic record

The operator reviewed a 2021–2026 illustrative opex series against ledger archive and Map v4. As-reported change was +$1.8m; restated change was +$0.6m. The $1.2m difference is the illustrative map effect, not organic growth. A second check found $0.4m for a disposed entity in 2023; Map v4 excludes it.

The first narrative—“opex scaled with revenue”—was rejected because it did not identify the map change. The retained output named map version, grain, currency rule, disposal exclusion, and as-reported versus restated values.

The [published CSV](https://infinisynapse.com/blog-media/multi-year-financial-analysis/downloads/recast-series-MYFA-MAPV4-20260823.csv) exposes four aggregate metrics. The [verification script](https://infinisynapse.com/blog-media/multi-year-financial-analysis/downloads/verify-MYFA-MAPV4-20260823.py) checks their arithmetic; it cannot reconstruct private source records.
