Tamping is done with a very specific purpose and the Barista puts a lot of effort into perfecting their tamp. Beyond the grind and the timing, you should remember that proper tamping is key to pulling a quality shot of espresso coffee. When you pull a shot, pressurized water is sent through the portafilter and into the coffee ground-filled basket. If you leave those grounds in a loose pile, the water shoots right through them. The water needs to force its way through the pile, when the coffee grounds are tamping.
A correctly performed tamp will result in even distribution of coffee across baskets. Also the coffee is at the same across the whole filter basket ensuring that there is not more coffee on one side then the other. Making sure to compress the coffee. Avoiding any pockets of air or cracks in the coffee grinds. This is again to ensure that there are no easy paths for the water to pass through.
