Not that it matters much for the result but.. My opponent only wrote "Djokovic" on the tennis question - and got the point for it. Am I to believe then that filling out the question as you tell us to, does not matter?
Yeah, these are a bit marginal. We never penalized them, we would if he wrote Federer - Nadal, Federer for example.
If the answer is only 'Djokovic', that means that we would accept him as the winner and also as one of the finalists - because you have to play in the final to win. So, 1 point because Djokovic lost, would have been 2 if he actually won.
Same thing on Cup penalties for example - if you write 4 answers instead of 8 you still have a chance to win - it's just smaller.

Bottom line - we will avoid penalizing players whenever we can. If they write incorrectly, they reduce their chance of winning already.
