How the model reads against Carnes' data

Fan power through the fan laws, one curve per fan from a US multi-rating table

1 632 cells over 14 fans; 230 withheld by name

every held cell's BHP within 2 % plus the half-hundredth it is printed to (the worst at 0.985 of that band; 20 cells from 0.5 BHP read past a bare 2 %, to 2.7 %) and its speed within 1.12 %, read back by the solver's own fan-law solve; RMS 0.69 % on power over the 1 280 cells from 0.5 BHP up. The twin tables are derived from the singles, so 893 cells are printed twice: the 764 held on both sides agree (the same rpm, twice the BHP), and of the 30 pairs that do not, the print the fan laws read off is withheld — the single 18's whole 1/2 in. BHP column among them. 178 cells sit left of the forward-curved wheel's pressure peak, in the dip the falling curve does not reach, and 22 read off the fan laws; both are withheld by name. Each rating lies on its curve (the curve's static at the design flow within 0.79 % of the design static), the curve's power within the motor up to the design flow; past it the forward-curved wheel's power passes the motor on 13 of the 14, and the record says where
