I would still prefer everyone just start at 1200. It's true people would drop to their real elo eventually but some never actually play that many games. I just don't see the logic in starting people with their choice at 2000 since so few people are there and above anyway that such a feature is pointless.
Your first game changes your rating by 300-400 points. It'd take 5 games for a 400 player to get to where he's reasonably accurately rated if he started at 2000 lol
??? 5 games???
In US chess currently until you've played 26 rated games, you rating is considered provisional. That is a rational number given what ELO is meant to estimate (relative playing power between players)
When I was a boy... back in the Late Bronze Age... we started at 1200 and LIKED it.
... none of this "I'll just start at 2000" crap.
