Club championship of the CIS countries.

And one more thing - the winners in most of the qualifying rounds are pure SOD players:
- in Kyiv - Aldegir - pure SOD
- in Michurinsk - Leha - pure SOD
- in Moscow - Eddie - pure SOD
- Siberia - Van - pure SOD
Therefore, you can count "most" like this ;) - 4 out of 7 for SOD, and only one - Yekaterinburg - for TE.
Statistics is a tricky science :)

Since Yekaterinburg was mentioned, I'll add my two cents to this statistic... as I understand it, all the qualifying rounds were held on SOD (Lite), so what's so surprising that SOD players won? ... if you hold them on TE/WT, I think the picture will change, and quite drastically.
And if we're talking about the matter at hand, it would be better to install all versions on computers... according to the rules, let there be one version, and the opponents can agree among themselves, I hope this is not prohibited?
