The good news is that we have a batch script that pulls the white to the far end of the spectrum. Additionally we have worked on the camera profile of the d100 to push the end of the white curve to the VERY far end. SO a short answer is about 9 seconds per shot and about a minute and a half per full rotation. That is not bad. When we started we editied every image. Our R&D department worked for a year to work it out.
Now their are draw backs. The "small" rig will shot objects up to 2' x 2' x 2'x , but if it is a solid object, like a tackle box or a television, we can not auto correct the image.
A case in point is a tackle box we are working on right now will have to have the shadows removed from the image. This takes about 3 to 5 minutes per image. Not to bad, but in this one shot there are 1700 images. It has a large amount of animation. To make things worse, the tackle box is a demo shoot.
