When using the default configuration (i.e., not changing any of the inputs) the maximum acceptable effort will be 100%. The default input settings assume that the simulated task is performed one time (i.e., a one-time maximum capability). If the inputs are changed to reflect a task that is performed more than one time per day, the maximum acceptable effort will be scaled down from 100% to reflect that one cannot work at their maximum during repetitive work. The scaling factor is described in Potvin 2012: (https://pubmed.ncbi.nlm.nih.gov/22624285/).
