Here is a lego plot of a possible problem in the small cells. 
r16129022 is at the beginning of a store and r16129039
is at the end of a store.

I have a lego plot of the number of hits for ADC>33 for only SMBS3 triggers:
for r16129022, the Yale cells are much hotter than the Russian cells, but by
r16129039, the acceptance is much more uniform.
