What are the amount provided by two silver badges for my account? My profile currently shows 5 GP and 9 SP which makes zero sense. Keith Sloan
Without getting into the details of the coding, it seems that after a certain threshold, SPs are rolling up into GPs. With single badge accounts this wouldn't happen but with multiple badge accounts it seems to be an issue. We're working on it.
There is a direct answer to your question as well. According to this page, for each Silver Badge you get 2 GP and 30 SP. That page is a great resource.
