In the features.json file that comes in the V4 data we have the following feature set sizes:
- small: 38
- medium: 472
- v2_equivalent_features: 304
- v3_equivalent_features: 1050
- fncv3_features: 420
Does anyone know the mapping between the 304 V2 features and the original 310 legacy features?
A further question: what is the purpose of the FNCv3 features? I’ve looked for documentation on this but cannot find it.
