Not expecting more than 1 to 3 LI to 84. HOWEVER, November 2018 NAM and HRRR were showing 6 to 8 before the changeover during that Months SWFE even though all the globals had C to 2.
Obviously that's an outlier, however shows that you are correct in it's important to keep an eye on the mesos to catch any surprises.
Same positive surprise happened during the March 2011 SWFE.
