I've more than once counted votes (paper votes) in Germany. We have the idea that counting should be done in such a way that the actual result is given to the next higher stage where the votes are added.

So if someone from the opposite party says he has counted 143 votes for his party and I count again (we always double check), most likely I will count 143 votes too and if I count 144 or 142 we'll count again together with a third party parson watching.

I would never trust computers.
