As an example of what can be done using
FREE Canadian track programs, here's a spreadsheet the pulls info from Mohawk Programs and creates/compares probabilities based on 5 different factors.
This is not a finished program and fails miserably on Maidens and 11/12 horse fields. I post it simply as an aid to those creating their own track program.
To use it you will need PDF-Exchange Viewer to open the Mohawk program and set the tools menu to 'text select'. Other PDF viewers will not work.
Good Luck
