Short tracks are often those that offer more interesting racing, specially those where it is harder to use all engine's potential.
But what ever length of track is, there should be lot of laps, more than 10 is needed for longest tracks and of course more needed when track is shorter so that you can't make low pressure tires to set and go as fast as in hotlapping mode, racing should not resemble hotlapping, imo.
Of course my opinion is coloured by fact that I do enjoy from tactical side of racing much more than winning
