interpolateTo woe - Macromedia Director 3D

I'm using interpolateTo to rotate the world model which comes with the 3d speedport obj convertor. When the rotation is finished I put a blob over it to indicate a location. I find that the sphere visually gets to the correct rotation with an interpolated percentage of about 50% so there is a delay until the blob appears. As a workaround I check for negligible change in rotation.z and stop the interpolation. Am I missing something by expecting interpolateTo to need the full 0-100% range to complete an interpolation? Is it just unwinding a gimbal lock thing whilst the model ...

    Default interpolateTo woe

    I'm using interpolateTo to rotate the world model which comes with the 3d
    speedport obj convertor. When the rotation is finished I put a blob over it to
    indicate a location. I find that the sphere visually gets to the correct
    rotation with an interpolated percentage of about 50% so there is a delay until
    the blob appears. As a workaround I check for negligible change in rotation.z
    and stop the interpolation.
    Am I missing something by expecting interpolateTo to need the full 0-100% range
    to complete an interpolation? Is it just unwinding a gimbal lock thing whilst
    the model is visually stationary despite interpolateTo being performed on it?

    And there I was wondering why I why getting such a nice effect as what I thought
    was a default behaviour!
