ModelCensus toolkit · modelcensus_fmi4.4_any_pptxfromexcel_v1.txt Use case: using an LLM to compile a PPTX from an Excel workbook Failure mode: fmi4.4 Right number, wrong unit · https://modelcensus.org/fmi/fmi_4_4 Model: any · Version: v1 · Published versions never change; an edit is a new version. License: CC BY 4.0 · ModelCensus (modelcensus.org) What goes wrong in this use case Headers carry units the model ignores: revenue in $000 on one sheet, targets in dollars on another. Compare them directly and every attainment figure is off by 1,000x. The guard Read the unit in every header you use. Convert everything to one unit (dollars) in the numbers table before any comparison, and write the unit beside every figure on every slide. How to check it Every figure on a slide has a unit, and no comparison mixes units. Example Revenue ($000) 2,184 = $2,184,000. Target ($) 2,100,000. Attainment 104.0%, not 0.104%.
