The strategy seems to be to use as many ways as possible to cheat the system. Then if somebody happens to find a way then the number of votes switched will not be enough to change the election so they can ignore it.
Another strategy is to make the vote difference enough to avoid an automatic recount but not so many that it becomes hard to fake all those extra ballots. 48% to 52% is quite a popular result.
