That's about right.
Maybe three of Russia's greatest leaders were Ivan the Terrible (a madman), Catherine the Great (a notorious nymphomaniac), and Stalin (one of history's greatest mass murderers). Yet under these three leaders, they accomplished some great things. It's a fair indication of their bad luck or aptitude with leaders.
There were other great Russian leaders. Peter the Great or those who managed to free Russia from Mongol/Muslim rule or the one who helped Europe to defeat Napoleon and to stabilize the continent for generations.
