Answer
The spinning gyroscope has slowed down.
Work Step by Step
See equation 10.33, which gives the precession angular speed: $\Omega = \frac{wr}{I\omega}$. Over two minutes, friction causes the angular speed $\omega$ of the spinning flywheel to decrease by a factor of 2, which doubles the precession angular speed $\Omega$.
It now takes half as much time to precess 1.0 revolution as before.
