Dear EvAAL organizers,
We have also found important inconsistencies on the results provided. The
most important problems we have found are related to randomly duplicated
samples in your input file for each test which lead to truncated test
samples on our side.
For this reason, we are recalculating the results and we will provide you
the report asap.
