The 2000 is 100% better than the 1000, but the 4000 is only 33% better than the 3000.
It's utterly shameless and ignorant comments like this that keep this otherwise forgettable topic going.
It goes without saying you're wrong.
Unfortunately this topic is too ridiculous to be worth commenting on (at least regularly) for anyone who knows anything... so there's a proliferation of silly comments such as yours.

Yes, the 4000 would crush the 3000 just like a 2000 crushes a 1000. ELOs are relative, so if the 3000 ELO was a perfect player and couldn't be beaten, then noone could attain 4000 ELO.
Quite true I agree
False. The 2000 is 100% better than the 1000, but the 4000 is only 33% better than the 3000. In addition, a 3000 guy (or computer) would know every drawish opening until the end, no matter that the 4000 was superior in the middlegame or the endgame.
