Thanks for the heads up. Must be falling asleep to miss that one. The run
seems to have progressed ok but something died in the output (Aggelos?).
After deleting that result (just in case) the results look like this:

2.5.58 3 96 82.3 9 5.2 1.22
2.5.58-mm1 3 100 81.0 6 6.0 1.27

No problem.

Will have to keep an eye out on the code for more bugs. So far the contest
code changeover is showing far less variability in the results (good job
Aggelos!) which should make for more meaningful results.
