Even if their doctrines about the 144,000 were correct, I'm sure that number would have been reached by the end of the first century, not 1935.
In an article (in the 1950's, I think) they acknowledged this, citing a historical writing that said during the persecution by the Romans, more than 144,000 Christians met their death in a single or closely-related series of events. That led to a QFR in a subsequent issue, asking how this could be. Their lame reply: "Well, the apostasy had set in by then and these professed Christians weren't necessarily all TRUE Christians!"
Of course, the elder who studied with me never mentioned this.
