Thanks in advance.
Not even close 😛. If you've ever played a 2100 and then a 2200 player (100 points difference) you'll realize that even that slight number difference makes for a totally different skill level.

a 400 hundred point difference is the same across the board, regardless of the strata. Period.

I'm not sure I believe that. I'm a 2300 player approx (both here and FIDE) and I think I'm considerably more likely to lose to a 1900 player than beat a 2700, alas!
I think what is meant is that elo ratings are used to work out the probability of victory.
The probability that a 1000 player will beat a 1400 player is the same as a 1600 player beating a 2000. This statement can be true even if the difference in skill is far greater at the higher band.

Period? No way. It says clearly in the FAQ:
"New Rating = Old Rating + K * (Score - Win Expectancy)
K is a constant (32 for 0-2099, 24 for 2100-2399, 16 for 2400 and above)"
You can go from 2000-2099 in (like) 3 games but from 2100 to 2999 in (like) 4 games.
With the current rating system, an 800 rated player should almost always beat a 400 player. I can't prove it, but I can't help but think that it is much more likely that a 800 player would lose to a 400 player, than a 2100 player would lose to a 1700 player.
