I think a light day every wednesday would be very useful once the working weights start getting close to 1-1.5xBW for squats and deadlifts. When I did SS I made swell progress right up until just shy of 300lbs which was then about 1.5xBW, after that I believe I had my first run in with overtraining, and instead of deloading, I just threw in a light day of olympic squats just to get some blood flowing and have a change of pace. After a few weeks I was back to making progress and I definitely owe it to that light day. Was much better for recovery for both body and mind.
Cliffs: Light day on wednesday after weight starts creeping towards 1.5xBW.
