As long as you have Statbook version 3.2 (or higher), this is now possible. Be sure to check out the Videos Page for a short tutorial on how to do this. The basic steps are as follows:
- Go to the Games Input and change all your partial innings to .1 or .2
- For every report and every statistic which uses Innings Pitched (i.e. IP, ERA, WHIP) you will need to select that field and use the corresponding "Favorites" formula
