Yes of course people prefer PGN.

Yes, this could happen in extreme cases. I believe that in Century 3.0
I have thrown out all the code so ALL games are saved as "unclear"
since you never get a 100% reliable score.

This might be quite user-unfriendly, on the other hand people are forced
to go through the games manually and replace the score with the correct
one, according their own opinion.
