All new sections have been changes in the method of calculating the average speed. For puzzles that have decided no more than 7 times, as before, the arithmetic mean of all speeds. For the rest - use the median (the speed of the player in the middle of the table decided on the speed). This will make the figure more informative and useful. Due to the fact that there are cases where some players have to solve intermittently, and can take other cases, while not closing the tab, the result greatly distorts the average speed. The median value for a large number of known results, gives a more accurate description. #of novolisina
