Interim Standings

After four snow storms...donsutherland1 moves into the lead...trailed by shanabe...who moved up from 5th and dmcguriman holding in third.

Under the ‘two-thirds’ rule…forecasters who have entered at least three forecasts are included in this interim summary.

Forecaster storm summary data here.

SUMSQ errors for each contest snow storm are normalized with a 'Z-score'...then averaged to compute the standings. Forecasters who have entered at least 2/3 of all snow storm contests are included in the standings.

If a forecaster has participated in more than two-thirds of all snow storm contests...then Z-scores from two-thirds of their best forecasts are used to calculate Interim and Final standings. Same idea as dropping the lowest quiz score before the final grade is computed.
