There is one savant that can do crazy math but is otherwise normal. Afgter an epileptic fit. His system is base 10000, he can add any two numbers below 5000 and come up with a single digit response in one loop. Then covert to base10 for the rest of us. Each digit in his base 10000 system has a different visual representation, like we have 0-9. It's integer accurate so I don't think it uses sine wave approximations. Guy can remember pi for 24 hours. I don't think the boffins or he himself got close to understanding what is going on in his head.
