Rating too hight for Tournament

Does anyone else get a little peeved when someone with a rating too high for the tournament joins anyway?  Is there any way to stop this?  Or, worse yet a players rating "mysteriously sinks" for a few days, they join the tournament and blow everyone away.  This takes all of the fun out of a tournament (for me anyway).

just venting..

"Often people who are not familiar with the nature and limitations of statistical methods tend to expect too much of the rating system. Ratings provide merely a comparison of performances, no more and no less. The measurement of the performance of an individual is always made relative to the performance of his competitors and both the performance of the player and of his opponents are subject to much the same random fluctuations. The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind. -- Arpad Elo, Chess Life, 1962"

Ratings change and when at a low point a player can join a ratings limited tournament and subsequently have a rise in rating. The solution is for TDs to set the rating limit lower than actual.

Here the actual is 1600 but the limit is 1550.  http://www.chess.com/tournament/match-play-three-day-time-test

Yeah. Some players love to play the higher rated players, some players love to play the lower rated players.

But I think it is silly for any TD to create an open tournament with 5 players or so. I think a range of 200 is good enough. For example 1800-2000, 1900-2100.
