Manual HDL/LDL Override Summary

Daily Summary Graph
• For this analysis, we captured unique HDL/LDL overrides– An override is considered unique if that same Resource did not
have an override within the last 10 minutes• There were 21 total unique overrides in February
– As compared to 13 in January and 13 in December

Reasons for Manual HDL/LDL Overrides
• An override is considered unique if that same Resource did not have an override within the last 10 minutes
• The “Other” reason given was QSE requested testing
• Congestion concerns were a result of inaccurate Resource telemetry
