Hello,
you should also use the harmonic average instead
of the arithmetic one:
harm.avg. = N / (sum_{j=1..N} 1/t_j) )
It weights small times with a greater weight, and
is somewhat canonical when dealing with speeds:
If you first need t_1 and then t_2 for the same distance,
then the time related to the standard-averaged velocity
is just the harmonic average of t_1 and t_2.
We could ask the players from mag-heut.net to send
us their complete 0.92-enigmarc2's. However, this
won't work for most of the new levels.
Greetings,
Andreas

The 10% quantile score? (i.e. score such that 10% of submissions are better)?
