I have sold over 200 T-bolts and had to replace about 30 of their thermometer chips, 
most because of the revision problem causing the 'stepped' temp plot, but some 
because of chip failure. If this were the typical low res problem the yellow trace 
would show the characteristic uniform staircase steps, not the random jumps to 
some common  value that it never exceeds. If you look closely at the plot you'll 
see many very small changes that are far smaller than any of the steps would be. 
Also there are major portions of the trace where it is absolutely flat and I doubt that 
this is really happening. I'll stick with broken but maybe someone else with another 
NTBW50AA can run LH and show what their graph looks like.
