While ten total experiments were conducted and validated against the open-Box and black box models, the results below are for three select experiments.
However, no matter how good fit of the short-term prediction, two of the three black box models do not seem to have satisfactory simulation tests, indicating that good short-term prediction does not mean that the model has captured the true process mechanism.

The other model proposed, the black box model to predict TTL, generalized well, and provided good predictions for the group of young fit males.
The sensitivity analysis for TTL using the black box model was performed under average environmental conditions (Tair = 34.
