That is VERY interesting. In its heyday, the 1980s, TWI was said to have about 40,000. Karl Kahler's book, The Cult That Snapped: An Insider's Journey Into The Way International, has lots of facts you might be interested in reading. Like this info on numbers, which is included (here's a shameless advertisement ) in my own new book, Undertow:
Author Karl Kahler states, “Cult numbers are notoriously hard to pin down, and are often inflated by anti-cult writers more concerned with sounding the alarm than checking the facts. Many writers have claimed The Way had 100,000 members, as if everyone who ever took the class were still a member. Around 1982, when [Craig] Martindale [second president of The Way International] was marching in Ontario and Way leaders were talking to the press, I heard consistently that we were claiming to have 40,000 members.” Karl Kahler, The Cult That Snapped: A Journey into The Way International (Los Gatos, CA: Karl Kahler, 1999), 110.

So, it is HIGHLY doubtful that today TWI has 45,000 like they told you. Actually, more like impossible, since thousands left in the days after Geer read his paper.
