Winter '17 / '18 - Regular Season Interim Standings: 6

Under the ‘two-thirds’ rule … forecasters who have entered at least SIX forecasts are included in interim standings #6.

 ---
SUMSQ errors for each contest snow storm are normalized (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 quiz score before computing the final grade.
