Misleading? How?

85-90% being reelected means 10% - 15% lose, retire or die.
That turnover rate is way too low. It should be no less than 60%. Term limits or smarter voters?
Term Limits? Supreme Court says term limit laws are unconstitutional for federal office, so you would need a Constitutional Amendment. Good luck with that one.
Smarter voters? Since the Federals have taken control of public schools and dumbed down the population to the lowest common denominator. Good luck there.

Misleading? How?

Simple. The incumbents who KNOW they are likely to lose don't run for re-election. You still have the turnover, but you don't have the incumbent losing.

A LOT of House Dems did NOT run for re-election in 2010, so the seats were technically open. A lot more incumbents would have been defeated in that cycle if they bothered to run.
