Yesterday I found the article with fresh figures which are presented here:
Yandex - 49,46%
Rambler - 22,27%
Google - 12,38%
Mail.ru - 5,12%
Aport - 2,29%
enjoy...
Yandex 3118 (Site ranks #2 for best single keyword)
Google 1586 (Site ranks #5+6 for same keyword)
Rambler 841 (Not in top 100 for same single keyword, but #4 for best phrase)
Google Images 260
Yahoo 224 (Site ranks #9 for best single keyword)
MSN 213 (Site ranks #4 for best single keyword)
Altavista 35 (Site ranks #17 for best single keyword)
Other SE:17
Total SE: 6294
This certainly confirms the strong standing of Yandex and Rambler, but indicates that Google's place is somewhere between them.
There's a lot more to identifying country traffic then a number of referrers or a site position for a specific keyword.
Plus your stats are for 6 month, I presume? That's a 1000/month - a bit small (no offence) to draw statistical conclusions.
Look at Alexa rankings (although I believe alexa penetration is pretty low in Russia, which just means that these sites should in fact rank higher):
Yandex - #363
Rambler - #637
Mail.ru - #380 (but most people are there to check email, not to search)
Google.ru - #1895 (russian version of Google)
