It has been awhile since I played with chronopl(), but at the time, I convinced myself that results were substantially different from penalized likelihood as implemented in r8s. I haven't explored this exhaustively, but at the time, I was very much convinced that the results of chronopl were potentially problematic. Other folks have mentioned to me that they've observed similar differences between r8s and chronopl and that they've recovered bizarre smoothed trees from chronopl. Perhaps someone with more recent chronopl experience can weigh in on this...
