Methods and devices for a feedback loop system, associated with delivery of content related to a software application, are disclosed. A method includes determining, for the content, a difference between a target output and a performance output. The performance output is an aggregate of respective unit outputs for unit(s) of the content. The method includes determining an input value required to re-perform at least one of the units. The re-performance can modify the difference. The input value, based on a probabilistic calculation of possible outcomes of the re-performance, is normalized based on a pre-determined baseline input value. The method includes determining, based on the normalized input value, an adjusted unit output associated with the re-performance. The method includes generating, based on the respective unit outputs and the adjusted unit output, and providing for display on a GUI, a graphical display layout comprising a visual representation of the unit(s).
