If yes, all of them would get the same round rating.. and the sum of the rating variances would total to zero (i.e. the round would rate somewhere in between 800 and 1000, depending on the exact number of players in each division).

Here you assume that they are playing in same tournament ie their scores get combined? But if 800group played independent competition, everyone shot the same score, wouldn't they get rating of 800 (zerosum game, no other information) whereas 1000group would end up with 1000rated rounds?
