Russia has been the nation to beat in Synchronised Swimming since winning their first gold at Sydney 12 years ago and are the clear favourites at London 2012.
Their technical routine was judged to have been just 1.800 off perfection yesterday and today the judges awarded them a total of 98.600.
When combined with yesterday's mark, that gave them an overall result of 196.800 out of 200.
China go into the final in second place, with Spain third.
Ischenko said: 'Today we are maybe about 90 per cent happy. We have small things to fix for the final. I hope the judges did not see the mistakes our coach saw.'
