Since PokerStars announced today that they are changing to a weighted contributed model of distributing VPPs (see this post for the full list of changes), we decided it would be best to have a Weighted Contributed Rake stat easily available for use in PT3.
Attached to this post is a zip file with that stat. To import it, download and unzip the file. Click Configure --> Configure Stats, change to the Stats tab and click Import. Choose the Weighted Contributed Rake.pt3stat file that you unzipped and click OK. After the file is imported, you can add it to any report which uses Player Statistics stats - for example, the bottom report on the General tab is one such report. To add the stat, click the small wrench icon at the top right of the report, locate the new stat in the list and double click to add it to the display.
Please note that if you are going to use this is any HUD layouts you will want to update your cache after importing the stat.
