There is actually a bug. When one or more games are not properly
"finished", e.g., no resignation is recorded, gnubg will include the
luck from these games in the luck adjusted result.

Three solutions:

(a) calculate an actual result from unfinished games by using a 0-ply
    evalution
(b) exclude luck from games where no winner is recorded
(c) try to calculate the actual result based on the score from the
    following game

Without much thought (b) seems to be easiest to implement.

Yes, Kees van Doel has suggested to change this to

FIBS Rating difference:  68.2

instead of the relative ones reported now.
