> Accel-KKR’s investment in isolved, which the firm acquired in 2011, has generated a 19.2 times gross multiple on investment, according to people with knowledge of the matter. It pitched another continuation fund for isolved because the company has more room for growth, the people said.

If they haven't sold isolved, it means they are just saying it is worth 19.2 times as much as they paid for it. When they "roll" it into a Continuation Vehicle, they are effectively inflating assets by saying its value is 20x what it paid for and the reason is "trust us bro".
