In Photoshop, will there be a difference in quality when a raster is scaled down 25%75% once as opposed to being scaled down 50% twice? In both cases, the final size will be the same: 25% of the original.

The reason I ask is because sometimes I want to scale down an image that I know has been scaled down previously. I hate having to CTRL+Z (undo) a hundred times to the state where the image was in its original size. If final quality is not affected, I'd rather just scale the image down right there and then.

Will scaling down incrementally hurt quality?
