Last Thursday, I modified the allowed PV list to further exclude FMCS channels which do not exist in the vacuum subnet (/H0:FMC-.*_H2O_PRESS.*/ rather than /H0:FMC-.*/).  Attached is a plot of the corresponding reduction in broadcast traffic in the vacuum subnet.  The second plot shows this change (in 'Week 28') relative to the previous change (in 'Week 27') that eliminated most of the redundant broadcasts for reference.
