Depends on when my job needs. It is about 40mins each way to my job and usually I start work at 8am. Sometimes they need me at 630am or earlier. The thing is waking up earlier than 430 is hard for the sleep patterns. Some people can do it more readily than others, but 545am is my ideal. One thing I have learned though is if you plan to make it a consistent performance set your wake up/starts on a bell-curve or a steady line. Spikes in the schedule almost always result in downtime following.
