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.

Nova's vocal has zero splicing transients. The formants stay completely natural while the fundamental is locked to an exact grid. My 14.4k connection dropped twice trying to fetch this thread.
