He is a research engineer and near the end of his tenure. I spent my career as an engineer devising tests and pulling data out of them to learn. The older I get I would rather have the knowledge than the win. I still say he knew the answer and saw 3 cams that were right and used this test as a learning tool and let the next generation win and build their reputations, he just wanted a larger data set. You can actually maybe get that vibe from him if you watch his last few videos on the test. Pure conjecture based on someone who has a similar career (different field though)
