["incremental_ytd","Incremental releases of data with sub-annual resolution. Should be used with caution, as in many cases not all respondents are required to report at sub-annual frequency, meaning data coverage may not be complete. This data is also likely to be revised prior to its final annual release. E.g. the EIA-923 monthly or FERC Form 1 quarterly data releases."]
