Continuing from our previous problem, the ballerina, later in the evening, decided to add to her routine and performed some more pirouettes. However, she was a bit tired and was unable to count exactly how many she did. She only knew that after those additional pirouettes, the total number of pirouettes she did for the day was 314 less than if she had doubled the number of pirouettes she performed before dinner. How many pirouettes did she do after dinner?
