The statistical numbers are deeply strange. Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents. 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.

Nova's vocal has zero splicing transients.
