Dear Yung-jin Lee,

I do not own WINNONLIN, but I suggest that the point t_max, C_max should not be included in the terminal part.

I further suggest that the TTT (two-times t_max) rule should be implemented to restrict the number of points in the terminal part, provided that at least 3 points are available.
See this thread for the TTT rule.

May be the Akaike information criterion AIC (especially the AICc, small sample formula) is a better choice than adj. RSquare.
