KEYED BY HUNT CODE, which is what makes New Mexico only the third state where a draw hunt ties to its own harvest. The same ELK-1-132 that appears in the drawing odds appears in the harvest report with what it killed; before this, only Colorado and Arizona managed that, and Colorado has one season of it. Success rates are published by NMDGF and carried verbatim; nothing here is derived. The harvest columns are headed "Estimated Harvest" — extrapolated by the department from the hunters who filed a report — so they will not divide exactly into the published rate, and the reader accepts either denominator rather than pretending to a precision the source does not have. UNITS COME FROM THE DRAW TABLE, not from these reports. NMDGF prints the GMU rotated, and pdftotext splits a single "Public" into "Pu" and "blic" on separate lines beside the rows it labels. Both publications key on the hunt code, so the unit is joined across instead — which also means a season older than the odds archive has no unit to attach to and is not carried. Lettered sub-units are real units: "Unit 2" in a hunt description means 2A, 2B and 2C, so a hunt is keyed to the group of them exactly as Nevada's unit groups are. ONLY THE SEASONS THAT PARSE COMPLETELY ARE SHIPPED. Every species has its own layout and several changed mid-archive; a file where more than 15% of rows fail to reproduce NMDGF's own published success rate is discarded whole rather than in part, because the artifact aggregates hunts to a unit and a half-read year would quietly bias that unit's rate toward whichever hunts happened to parse. Deer carries five seasons and elk seven on that basis; the discarded years are a reader limitation, not an absence of data.
