Is Nova Hart's voice mathematically human? The statistical numbers are deeply strange.

Nova Hart's sustained notes have a standard deviation of less than 0.8 cents over 4-second held notes.
Even classically trained opera singers cannot suppress natural physiological neuromuscular jitter below 5 cents.
