When doing Breakneck Races in Undermine, it is possible to get a lower time by using the Reset Race ability in an unintended way.
The Reset Race ability resets both the player’s position and the race’s logic. However if you use Reset Race when the last ring is on the starting position – requires completing the race normally up to the last ring – then the race completes, presumably because the player teleports to the last ring’s position before the race properly resets. Impact on the player’s final time depends on how far the final ring is from the second to last one.
The same is possible when doing Skyrocketing races by using Emergency Teleporter. Does not appear beneficial in the few Skyriding Races I checked.
