4.7 - wow, one more percent to APS

Yeah I've always found, with this and other machine learning problems, that big ideas and better data help more than all the little bits of tuning which tend to take up the most space. Although the lack of classes is also just my style of coding, I actually find I can hold more of it in my head if I don't devote too much of the bot to structure, even if it is messier. It allows me to focus on algorithm and behaviour, rather than implementation details and constant refactoring.
