Currently the final time is based on the Final Time at the end of races. This allows for knocking time off by Tricks, Air time, and most importantly Snowball + Takedowns. Its also not strictly "fastest".

Alternative idea is to used Elapsed Time displayed at end of races, which is a more honest assessment of how long the race took, with no benefits to style play.

For now Ive gone with the Final Time timer, because it allows for more varied play and strategies. If other runners disagree though, we could change it in the future. Let me know what you think!
