zoltan, I don't doubt there is 'something wrong' with your results, but I would guess your 'standard text' is discounted as 'boilerplate' text and not a factor in the ranking of your pages ... I'd look somewhere else to try and find the issue.
There have also been reports of changes in rankings and rankings returning lately ... I really don't think your 2 sentences was the issue, but I guess anything is possible.
