Did Charles Hatfield's Rainmaking Really Work?

In the 19th and early 20th century, luvoculturalists tried to prove that what they were doing was real by providing more rain than expected. Charles Hatfield claimed he had a very high success rate with his "rainmaking" It's hard to say whether their efforts had any effect because there wasn't much data about them at the time. But one way or another, I think it's entirely possible that he was sincere in thinking he was having an effect.
