I don't think they used the word "evidently" near enough to give themselves another "out" somewhere down the road. Let us help them out:
"Although we evidently cannot measure the exact length of “this generation,” we evidently do well to keep in mind several things about the word “generation”: It evidently usually refers to people of varying ages whose lives evidently overlap during a particular time period; it is evidently not excessively long; and evidently has an end. (Ex. 1:6) How, then, are we to understand Jesus’ words about “this generation”? He evidently meant that the lives of the anointed who were on hand when the sign began to become evident in 1914 would evidently overlap with the lives of other anointed ones who evidently would see the start of the great tribulation. That generation evidently had a beginning, and it evidently surely will have an end. The fulfillment of the various features of the sign evidently clearly indicate that the tribulation must be near."
I can just see the Writing Department letting out a collection sigh of relief after they sent this crap to the presses: 'Whew!! That outta hold everyone for another 60 years!"
We should all start phoning the Writing Department demanding an explanation. LOL!
