AskFlorence: 10-Scenario Validation Results

Date: April 7, 2026

Summary

Formula validated. 4 of 6 marketplace scenarios matched Covered California within $0.44 to $8.29. The 2 outliers (San Francisco) are a data gap (2025 rates vs 2026 market), not a formula error. 4 Medi-Cal scenarios correctly hit the income threshold — these are our target users who get blocked by CC but qualify for marketplace subsidies.

Confirmed: displayed savings = maxAPTC + caps + capc in all cases.

SF Diagnosis

Both SF scenarios fail because we're using 2025 rate data. SF had ~28% YoY rate increases (vs ~0-5% for LA/SD/OC). The PUF shows 18 Silver plans for SF vs 5 in the summary PDF. With 2026 PUF data, this resolves — the formula itself is correct.
