    You do not need to produce a display update for every pulse you get. Our human brain has a limited capacity - it takes a lot of time for us to read, and if you update too often then the last digit(s) on the display will be hard to see because every reading will vary a bit, making the last digit(s) constantly change value.

    If you have a sensor that produces a lot of readings, then you may decide to measure the time of 5 pulse periods instead.
