If that's true it's possible to see markers disappearing often (a lot of Heroic battles fought) or stay there for the whole of campaign (quite small number of Heroic battles).
The marker which I found undeserved (killing some random Eleutheroi with a BG and garrisson) disappeared earlier than the massive heroic victory against the AS.
