How many doctors did Sarah Jane star with?

Her main Doctors were 3rd (Jon Pertwee) and 4th (Tom Baker), she appeared on 'The 5 Doctors' where Doctors 1 to 5 met together and then she saw 10th Doctor (David Tennant) and then met the 11 Doctor (Matt Smith) on Sarah Jane Adventures

This shows that she was involved with Doctors 1,2,3,4,5,10 and 11 (7 altogether)
