Yeah, she didn't seem rattled that her tit was fully exposed for a bit (as seen in one of the latest comments on her content thread). So, if she's not going to panic about that, and even go ahead and post her lingerie clip to the public unedited with the slip-up included, it just makes it look like she's following the classic step-by-step plan of "always leave them wanting more."
She loves money, given that she celebrated making over a million by being near nude, so it's believable that she'll love making even more. Being rich has a way of turning people on, and she must know that everybody who was willing to spend over a million on her just for lingerie shots, (whether they knew what they were getting or not) will probably go back to her and spend the same amount, or more, if it's revealed that this time they finally get fully topless content. Once she makes all she can with that, it's reasonable to believe that everyone who spent that second million, will probably go back to her yet again and spend another million if she goes full bottomless. She can make her fans come back over and over by offering more and more as time goes on (solo, b/g and etc) and it will work.
If she burned through every kind of content she's willing to make right now, her peak income would be higher due to a wider pool of people wanting to buy her stuff. However, it would probably end much quicker because she would have nothing else to offer in order to make fans come back and spend the same amount a second or third time. Of course, that's unless she has a great personality that draws people in to "her world" and becomes an online personality, but that's a business that's harder to maintain over a period of time. So, she probably feels like drip feeding her fans increasingly explicit content is working right now, so why change anything?
