Character classification is the easy part of OCR. EDIT: It sounds like they were benchmarking a very constrained problem as well (only a single font, with certain features). One disadvantage with Tesseract is that it has to be trained by the user for specific fonts, my OCR was generalist (general shape-based character classification is practically designed for convolutional neural networks). I'd love to give more details in a blog post soon.
