If there is a deadline, possible strategic surprise moves might occur just 
before that deadline. One alternative (quite theoretical) approach (that would 
be more difficult to the strategists) would be to continue the election until 
the situation is stable (stableness to be defined, maybe with time as one 
parameter).

The problems of Approval might remain and even get stronger.

30: A > B >>
30: B > A >>

A and B supporters could fight for the victory and decrease the number of 
approvals of the other one of them, and these sincere opinions might in the end 
become...

10: A > B >>
20: A >> B
10: B > A >>
20: B >> A
40: C >>

Now all candidates have 40 approvals and the situation is unstable.

In general this approach makes strategic voting easier since the (current) vote 
counts are known. In some situations results could also improve thanks to the 
same information about the other votes.
