A generally interest question I want to document this morning Step 1 - Create a condition from the last sample till "Now" $caps = $MySignal.toCapsules() $timeSinceSample = past().subtract($caps) $timeSinceSample Step 2 - Create a Scorecard to Capture the duration of the condition created in Step 1 Make sure the Maximum Capsule Duration is longer than the longest gap you would expect in your signal. In this example it is 180 days
