Thats not how it works. =_=

Basically, the optimum range is basically how well the range is covered by recorded samples. The more you go away from the range covered by the samples, the worst the result is as Vocaloid has to improvise more and more. If she can go deeper and handle things better, then it means the maths done by Vocaloid is doing its job better, not worst.

Vocals in Vocaloid often have vocal collapse outside their favoured range, be it too high or too low. Ergo, it doesn't matter how deep she is, its how well she handles it that determines if the range is bigger or smaller. This is why recommended ranges, as well as tempos (as a vocal can only handle X amount of speed), exist.
