Winter '18 / '19 - Regular Season Interim Standings: #1

Under the ‘two-thirds’ rule … forecasters who have entered at least TWO forecasts are included in Interim standings #1.

Forecaster statistics for Winter '18 / '19 Regular season snow storm contest here (direct link)

SUMSQ errors for each contest snow storm are normalized (i.e., standardized) with a 'Z-score' ... then averaged to compute the standings. If a forecaster has issued forecasts for more than two-thirds of all snow storm contests ... then Z-scores from their 'best two-thirds' forecasts are used to calculate the Interim and Final standings.

Similar idea as dropping the lowest test score before computing the final grade.
