Specifically, it does not provide past scores for h2h records to be accounted for nor division records, points, etc. It may still be workable if the league only uses points or division records as tiebreakers to manually input necessary data in the "Team Info" section.

Important notes and warnings: This tool, made by somebody with minimal programming expertise, attempts to have a device do super-computer tasks via an almost infinite number of calculations over possibly extended amounts of time and is strictly 'USE AT YOUR OWN RISK'. Once one of the 'Analysis' buttons is clicked please be patient as the processing time varies from a few seconds to many minutes or even hours depending on the options chosen and complexity of the inputs and scenarios. On most browsers a spinning circle will indicate the process is ongoing. If a browser message appears similar to 'web page is not responding' ignore it or select 'wait'. When the process is complete the results will be displayed on the screen. It is recommended that the device be left alone during the processing and that all other programs and windows be closed to dedicate computer resources to this, other than a 'Task Manager' window running is suggested to monitor CPU usage and can serve as a visual indicator in case the program 'crashes' while the spinning circle continues. Please see the full instructions and videos for additional details. Some of the tips in those can save one a lot of time.

Verify inputs above before clicking on one of the 'Analysis' buttons. Watch for accidental mouse or touchpad movements changing the input on specific cells and doublecheck the options selected. The calculations are made soley based on what data and inputs are shown above, whether correct or not.
