The AVS should be in the owners handbook - it is now a requirement but not sure whether it was in 2012. initially when the RCD came in in 1997 the intention was for builders to make a full set of statistics available and for a time this did happen and it was common for magazine tests to publish the full stability curves and STIX values in reviews, but over time this seems to have stopped.
Bavaria (like many other builders of mass production boats) have always been reluctant to release full statistics, only what is legally required.
