Not a Boeing guy, but the AEO go distances, the ASDA distances at 24K loom reasonable on their deltas; but the rated power OEI go distance is the outlier—900-ish meters is huge. Their must be discrepancy in the V1 that was used versus the “policy” V1 i.e, it used V1min rather than policy V1. That would explain it—long time accelerating on one to Vr. The 46 knot delta between rated and reduced power min V1 is suspicious, too.
