I would honestly myself say drop the reps and keep the load high. Just for the sake and purpose of this program dont go to failure, and try and advance every w/o be it by load rasied or reps at set load raised..
But, I imagine both are viable choices. I am thinking dont quote me however, that Chad had previously said to Drop the weight.
All in all it sounds like the weight chosen may just be to high all together.
Clear as Mud HUH??
Hope it helps somehow,
