To optimize phase orders:
   Check the "Optimize Lead/Lag Phasing" option AND
   Set "Allow Lead/Lag Optimize" to YES in the Phasing window.
Performing a complete Lead/Lag optimize may find even greater
   timing improvements.
Combining these suggestions may reduce total delay more or less than
   the sum of the improvements.
WARNING, Permitted left turns should not be used with lagging left turns.
All delays listed above are uniform delays only.  The incremental
   portion of delay is not affected by offset optimization.
