In the early days of the CC, it was a race between two sub-teams, so the "change required" was used to identify the points of the sub-teams, from their parent team.
After the CC became a whole team race, that need was obsolete, but has been used as a kind of "loyalty" or "elite" test by teams - and of course, required by the CC.
For (going on) 5 years now, we've been hearing how the racers want to be able to keep their own folding handle, while they race. I wasn't in favor of it before, but changed my mind when I saw the internal dissension that happens to teams when they join the CC (some folders won't change, others insist they should, name calling starts, etc.). I've come to the conclusion that not requiring a name change, is the better path forward for the CC.
There are ways to handicap this for the first CC that uses it, btw. Teams that have a high turnout now, won't be put at a disadvantage if it's used. A team that had 60% participation has their points basis from last year, bumped by 40%, for example. A team with 90% participation has their basis bumped by only 10%. A high basis, means you have more of a handicap to overcome in the race.
I can't keep telling folders that I hear their requests for no name change in the race, year after year, and not act on it. After five years, it's time to give this idea a chance. That's why I'm recommending it.
I can't recommend anything for Mars, but here's an interesting fact:
Over 400 people have already volunteered to be on a ONE WAY space trip, to Mars.
