PC Disclaimer: Buggy is a team sport, everybody that races wins, D-team is just as important and sometimes more so than A-team ... I can name the top 5 fastest women's times and year ... ok top 3.
When is it a good idea to put your brand-spanking, paint still-dripping, barely-qualified 1st season buggy as your Men's A-team contender? (this isn't sexist, more Men's A buggies crash than any other entry, look it up)
A) Everything else we have blows or is broken so ... minimum required rolls is good
B) Newer MUST be better so ... 1 or 2 rolls at full speed/treatment/a-team caliber hill 2 should do it
C) Must log within 1 sec of previous contender at freerolls and having something better about it like weight, stability, better driver, bitchin paint job [does not apply to pikes since they can't paint]
D) Must match or exceed previous contender at freerolls and show no stability/reliability problems.
E) To displace a proven contender it must prove itself on the only real testing grounds ... raceday.
