From that, I believe it isn't the throwout bearing. There is no noise at constant speeds during shift. There is noise however when I hold the clutch down too long. The input shaft begins to slow down and the pilot bearing begins to spin.

Release bearing always makes noise when the clutch is engaged if it is damaged.
Pilot bearing makes noise when the clutch is pressed.

I fear the throwout bearing more as that can disintegrate and get caught up in the transmission and cause failure.
