The reason why stats are presented like this is because they are easier to understand. Humans are poor at visualising large numbers (where "large" can be as small as 30). So reducing the time frame to give a number that people can work with is a reasonable thing to do.
Of course it's an average. If you want to know the spread, that's a different question (you want a standard deviation, or centiles, or whatever). It doesn't make the average wrong, or invalid.
