Indicator C4 — Schedule / Date Inconsistencies

AI-verified / Na-verify ng AI Data as of October 21, 2026

Schedule / Date Inconsistencies

Completion before start, implausible duration for cost, or future dates marked complete.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: contract 22A00289 (₱7.89M) is recorded as completed in 29 days against 29 planned; similar-cost projects take a median of 147 days, putting it in the fastest 0.6%. The project may have been unusually efficient or had a smaller scope than typical for its cost.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4

Checked: October 22, 2026

The project was completed in 29 days, which is extremely fast compared to the median of 147 days for similar-cost projects, placing it in the fastest 0.6%. All relevant data is present, and the anomaly is clear and checkable. Innocent explanations (e.g., unusually efficient work, small scope despite cost, or pre-fabrication) are plausible but do not negate the anomaly.
