She stated in her thread that her first time was when she was 11, and if she's 16 now, it means she had 5 years full of sex. 270 days are ~ 9 months. If we divide that into 5 intervals with each interval representing a year, we'd realize that she had sex with roughly 54 people each year( 270/5 = 54). That means for 1.8 months (54 days/people are ~ 1.8 months) of the year she was on her back taking a dick - and that is if you exclude the threesomes, and also assume she's hetersexual. So according to these calculations (if I didn't make any mistakes along the way) you have to have sex with a different person each week to reach 270 in 5 years (cuz 365/54 ~ 7), which is doable tbh.
