Since there is no official information on the web, I recommend that you use the User Guide or the Help available already within the application. Start the software, then go to Help > Help topics. Wait for the window to open, then switch to Search. Input Master Points and read about all the available topics.
Additionally, use the installation folder and look for the USER GUIDE in PDF format. There is also a page from the developers of PairsScorer with various documents: http://homepages.nildram.co.uk/~jasmith/UserDocuments.htm
