We have a number of options for the count depending on the player, instrument or vocalist. For fast tempos, one measure was not long enough, but ballads, two was too long. Some songs have intros, some people mute the count but need the 'auto time' then rely on the intro before singing or playing, others need time to pick up their instrument before the start. I think the options cover most people's needs.

Thanks for your comment, I do understand what you are saying.
