The current record [1] is in fact 26.59 seconds for expert. This doesn't make you an unofficial world record holder because, among other reasons, the chance is that you have encountered an easy enough board by chance. The most popular measure of board difficulty is 3BV, defined as the minimum number of left clicks to solve that particular board, and should be at least 100 for the expert record to be recognized.
