The top concordant period again shifts in a rolling alignmnet, matching the previous week's concordance with the 1982/83 period by moving forward one week. This involves a slight weakening in all three metrics.
A calendar alignment shift (similarity in dates) between last week's concordant period and this week's of one month later is present. Due to slight weakening of the three metrics, forecasts based upon this concordance should be comparable to those based on last week's top concordance in terms of accuracy.
