Lewis is definitely not a fairytale reader. I've gotten both negative and positive predictions from him, however there was an instance where he predicted very positive outcome, but the real outcome was more so lukewarm, not that positive as he highlighted it to be.
Another instance was when I called him last July for a product I was building, he said there won't be any traction on it, but when I called again last month, he said the product will do very well. I don't know if this is lack of consistency, or that the percentage has changed because I kept working on the product...
