For most cases normal performance practices/techniques should be used.An improved climb method brings with it many issues that reduce safety, like higher speed potential aborts for example.Bleeds off is a safer way to increase payload etc, and should be used if normal methodology isnt enough.Then consider IMPROVED CLIMB if absolutely necessary.At the end of the day, its up to both the operator and the PIC to decide the best/safest course of action.Aviation in general isnt a science (except for the laws of physics), its an art form and you are the artist.
