- Added loader and action functions for managing expected values in sports seasons. - Implemented UI for recalculating probabilities based on participant results. - Created a service to update probabilities after results are finalized, including handling finished and unfinished participants. - Developed tests for the probability updater service to ensure correct functionality. - Introduced a preview feature to show potential changes before applying updates.
