The top concordant period (1996-97) shifts a year later than last week's concordance. There is as yet no known historical parallel, other than concordance, between these periods.
The concordance drops further from the strong concordance of two weeks ago in all three metrics used, though Gini remains strong, despite further weakening.
Forecasts based upon this concordance must be expected to be less reliable than those based upon the past few weeks' matches, due to this weakening.
