Three to four hours of practice a day is quite a lot, in comparison Johnny Ho (http://www.quora.com/TopCoder/Who-is-Johnny-Ho) only did about 1 or 2 a day while practicing for IOI 2012 Source: me asking that exact question to him at IOI 2012 |

Also, this guy has been performing at an extremely high level for years. If he didn't do any competitive programming practice at all for a year, I doubt you'd notice a big difference in his performance.
Some of the top guys at Topcoder Open / Google Code Jam don't even participate in matches outside of the yearly tournament and I doubt they are practicing consistently (i.e. once you get to that level at problem solving, performance doesn't seem to decay much and certainly much less than in a similar situation for athletes - though these guys are students / engineers whose brains are still being stimulated and solving other kinds of problems outside of competitions).
