Samalog is a scoring system in speed skating. It is used in allround tournaments to convert results at various distances into points in order to determine an overall champion. All times are measured in seconds and then converted to points, using the average times on 500 meter units; thus the number of points for a 1,000 meters race is the time in seconds divided by two ; for the 1,500 meters, the time in seconds is divided by three, and so on. Points are calculated to three decimal places and truncation is applied; the numbers are not rounded. All points are added up; the lower the score the better.
