In ssms 2012 , the new extended event of inaccurate_cardinality_estimate is not shown in the extended events manager.

Additionally the actual row count is returned as (estimated rows *5)+1,  why not the complete actual row count ?  After all, if a statement has a 10* estimation error , then it should be investigated prior to a 5* estimation error.
