As we can see in row c), the percentage of ties differs across languages: the Dutch Pilot 2 was evaluated as equal to Pilot 0 only in 5.65%, while for Bulgarian it was in 58.10% of the evaluations.
we cannot compare the relative quality of Pilot 2 and Pilot 0 only based on the number of cases when Pilot 2 was judged strictly better than Pilot 0 (row a), or only based on the number of cases when Pilot 2 was judged better or same as Pilot 0 (row c).
