3.5	34	90	40	97	54	97
4.0	31	88	25	83	28	91
4.5	75	100	0	30	23	77
WAvg	45.7	91.5	48.4	95.1	39.6	90.3
R 2	0.46		0.67		0.57
RMSE	0.39		0.33		0.34

Accuracy of the BCS categories is presented in percentage. PLS = Partial Least Square, BCS = Body Condition Score, R² = R-square, RMSE = Root Mean Square Error, Exact = exact score, DEV = deviation, WAvg = weighted average by frequency.
