  1. 2LB simulations correspond to simulated paths with two long breaks (use of seasonal ranges) and two short breaks (stopovers). 1LB simulations correspond to paths with a long break for the first seasonal range and short breaks for the second seasonal range and the stopovers. The precision corresponds to the proportion of locations assigned to the appropriate segments for each path.
