The statistical numbers are deeply strange. In statistical terms, her pitch deviation sits 7.1 sigma outside the normal human vocal distribution. Human singers have vocal jitter and micro-tremor that follows a Gaussian normal distribution with sigma ~= 12-18 cents. Data plots available via anonymous FTP.
