Google Analytics calculates users per month bad!

http://ift.tt/294s1Eo As you can see from the picture in the link , highlighted with red are the users for each day of the month , with green is the real total number of users for the entire month and with blue what google analytics think is the real number ! My Question is why is google analytics giving a wrong number ?
