Hi TP. have you considered having last 42 days (and last 42 + next 7) as one (2) of the timescale options on the performance management chart. as CTL is the average TSS over the last 42 day it would be useful to look at so you can see quickly what TSS is about to drop out of the 42 day window (you already have last 28 days and last month which are so close that maybe you could drop one of them).
