I'm not sure about an actual amount of points we need but I would say we only need 1 more point than hearts get, as long as one of our victories is against St Johnstone.
if Mr Leveine can step up and get his team playing with the same level of performance that he instilled in the Scotland team we could see hearts slump their way to the end of the season. So maybe we won't need as much as 10 points ?
