Z supports

The Z supports loads did not load linerally during the cooldown. 
I left them loose to avoid breaking them during cooling and expected them to snug up toward the end of cooling. 
Toward the end they did snug up but toward the end they all dropped off sometimes to lower values than the zero cooling number. I have not figured out why. 

AND one would suspect that opposite load cells would load and unload at the same time, but this is generally not the case. see plots
