An average is a set of consecutive solves, in which the best and worst times are removed. The remaining times are then averaged together. Most competitions use averages of 5 for speedsolving events. There are a few exceptions however, most notably solving with feet, clock, and 6x6/7x7, which all use means of 3. The best and worst times in an average are placed in brackets. Example: (5.43) 4.32 3.21 2.10 (1.00)
If any counting time (a time that is averaged, not the highest or lowest) is a DNF or DNS, the average is a DNF.
Types of AveragesEdit
Average of X (AX, AoX)Edit
Many speedcubers use averages of 12 to gauge their ability because many view that averages of 5 can contain too much luck. Averages of 100 can also be useful in determining consistency in puzzles such as the 2x2, where virtually all mistakes count towards the average.
A rolling average is when you do an average, then continue to do solves. The first solves are then removed from the average and replaced with the newer ones. For example, if you did an average of 5 with (15.32) 14.64 13.17 (11.22) 12.88, you can do another two solves to remove your two highest times. The times that are removed are considered "rolled".
A mean is very similar to an average, except the best and worst times are not removed. Means of 3 are usually used when a puzzle takes a long time.
