it depends on type of ques. sometimes two points will be enough but you need to elaborate the points. and sometimes four points and such point should be precise and short.
Usually if it is four marks question, then four point suffices. Yes, the points need to be precise and within the boundary. Reckless or imaginary views should be avoided as far as possible, because then the examiner gets to know ur creating an artificial bubble and he or she is bound to burst it by cutting down the marks.
